I only needed to read the first half of your post, to start to see the problem that you're facing...
1) Please understand that these two desires you write about ("full keeled, heavy displacement boat", and "45 feet on deck, 32 feet at water line / below decks...considerably lacking..no thanks"), are contradictory....

I have also discovered that many a craft may have 45 feet on deck, but when you get below they are considerably lacking, like 32 feet at the water line. No thanks!
As most traditional "full keeled" "heavy displacement" sailboats, DO have long overhangs (meaning much shorter waterline lengths, than lengths-over-all)....
And, most also have narrower beams, and generally the max beam is only in a small area near the center of the boat, with both ends "pointy" (even the transoms)....
They also tend to have an old/traditional "sailor's" interior
design/layout that is more conducive to sailing than to living on-board, especially with today's modern lives / conveniences in mind...
These basic traditional design schemes, are what gives even boats with decent lengths-over-all / lengths-over-deck, that "considerable lacking" feeling in actual space below decks...
So, if you are dead set on your full-keel, heavy displ, traditional design...then you're going to need to accept some compromises in below deck accommodations and living space....
And, if you looking for some boats that fit your "full-keel" desires....
There is quite simply no other boat like her....and that's a Hinckley Bermuda
This Bill Tripp design, built by the finest yacht builder
in the world (Henry R. Hinckley Co.) is a wonderful, sweet, elegant, sailing yacht...with a full-keel...and with a D/L of about 390, she's deemed a "heavy-displ" boat...
Have a look...

Hinckley Bermuda 40 Reviews
I'm going to be very up front with my prejudice here and tell you that, personally, I don't recall a time when my sense of style, balance and proper proportion of sailing yachts has not been influenced by the design work of the late Bill Tripp. The Bermuda 40 is a quintessential example of Tripp's art and masterful eye for near-perfect balance.
With its classic long overhangs, perfectly pitched sheer line, wide side-decks, graceful cabin profile, and distinctive near-vertical transom, the Bermuda 40 has inspired severe lust in the heart of many a cruising sailor.
Unlike its contemporaries, the B-40 endured for a very long time, surviving both the advent and demise of the IOR regime that supplanted the CCA rule in the early 1970s. The first of these gorgeously proportioned hulls slipped down the ways in 1959. The very last hull, number 203, was launched over three decades later in 1991. So far this is the longest production run enjoyed by any fiberglass auxiliary sailboat anywhere in the world.
Another possible candidate for your specific desires, might be the Tayana 37
....maybe a bit small for you, but a nice boat, nonetheless....
2) Please be aware that the "heavy" in heavy displacement is of course a relative term....and since the LWL (waterline length) of the boat with the traditional long overhangs, increases greatly when the boat is heeled, the D/L ratio can be a very misleading spec to use when trying to compare boats....
(use of the SA/D ratio can be a much better way for initial comparisons to be made....)
Again, there are MANY things that go into yacht design that are well beyond this discussions capability to educate...
Just trying to hit the highlights...
3) Yes, I have experience sailing/cruising in a full-keeled, heavy displacement boat (Tayana 37).....as well as a modified-keel, skeg-hung-rudder, medium-displ boat.....and a modern fin-keel, spade rudder, light-displa boat...including many 1000's of miles offshore
and a few Atlantic crossings in them...

I only ask that if you differ, please be very specific as to why you do so....Additionally I am beginning to think I will never find a suitable candidate that can provide the living space below deck that matches the length of the boat above (or is at least close). I hope I'm not being over ambitious here, but long overhangs that jack up the LOA while the builders jam two cabins and a head
in 10 less feet below is ridiculous. I don't what to have to buy 55 feet of boat to get 39 feet at the water line. Can anyone relate?
Oh and no I don't have unlimited funds and yes I'm looking for a second, third or forth hand boat....but not a full blown project! I don't mind exchanging a reasonable amount of sweat equity in return for a lower asking price
But, I am confused by your questions....
You stated up font what your choice was....and you're asking what others choices were???
Not sure how that will help...as others; choices are based on THEIR desires, for THEIR application, etc....and YOUR choice will be based on YOUR desires for YOUR application....(and since you've made no mention what your application is...just writing, "My basic requirements as stated above are well founded in our intended use of the boat
"....we are sort-of in the dark here....yes??)
And, you do seem to be pressing the "full keel" and "heavy displacement" angles...but perhaps not fully understanding that there is a LOT that goes into sailboat design and engineering far beyond the "keel type" or its displacement, that govern the way the boat sails
, responds, etc. and even more important how sea-kindly, etc. it is....
And, many of these things are far beyond the capabilities of an internet
discussion board to teach....and many even require naval architects / engineers to fully flush out (certainly beyond my capabilities...)
But, if you're interested in others' choices...I'll oblige...
And, I'll include some photos of my boat as well as some reviews
/ quotes from yacht designers...(and maybe some videos...)
My choice for ocean crossings and long-range cruising, is my current
She is a 47' 6" LOA, 42' LWL, 14' beam (carried well aft, but not to extremes) 27,700lb displ, 9550lb lead ballast, sloop
.....with a modern fin/wing keel, a wonderful BIG spade rudder, and a well defined, full and round underbody and perfect-shaped forefoot, as well as a modified modern fine entry....
SA/D is 17.6....D/L is 167....B/D is 33%...LPS 130*...
She's very smooth and kindly offshore in a heavy sea...but also very fast and extremely maneuverable....
Have a look...

And, here are some quotes from Bob Perry....
Catalina has a new flagship with its in-house-designed 470. The overall Euro-styling reflects the degree to which some American manufacturers have been influenced by the imports.
But if you look carefully, you'll see that the overall styling contribution of this cabintrunk has been increased by keeping its side well-defined. Longitudinal lines like this edge will stretch out a boat's look. It's the same trick we do with carefully placed boat and cove stripes. It's Euro-Cal.
The D/L is 157 for the fin- keel version. The shoal-draft wing keel weighs 750 pounds more than the straight fin. Catalina must have been designing to a stability standard they wanted consistent for both models.
Again, in the European style, the stern has been kept very broad. This feature is obviously driven by the quest for more useable accommodation volume, but today we are at an advantage. We have watched the sterns on the best racing boats grow in beam. The cruising boat designer can study these wide sterns and decide just how to incorporate that advantage into both speed and comfort potential.
We did the same thing with the old 12-Meter-inspired bustle feature.
The galley is wonderful with a refrigerator that opens both from the top and from the front. The owner's stateroom, with direct access to the head, is palatial by any standard. This is a big boat.
When I walk through the Catalinas I get the feeling that the designers are using some of the same dimensional parameters as I use. I can relate to these layouts.
I'm not sure how helpful I've been, but I tried....
