You are all over the place on this. That's neither unusual or even inappropriate. But, you have to start somewhere, and looking at ads/specs or getting tours of various boats is not the place to start. You will only get confused by the endless alternatives.
IMO, the best and easiest (but not cheap) way for you to get started on choosing a boat is to do a one week crewed charter
in the BVIs. You want the Caribbean
; you started out thinking about a Beneteau
; and you can easily charter
one in one of the easiest and most fun Caribbean
sailing grounds. This will give you a baseline from which you can make meaningful comparisons with everything else.
The bonus is that with a crewed charter you can ask questions of an experienced captain
as they occur to you; you can get real sailing/living experience on the kind of boat you might be interested in buying
; you will get a compressed view of what cruising is really like; and you are almost guaranteed to have a blast. As I said this not cheap
, but it is money
