I've always like the C&C41 (mid 1980's) because it has upper "pilot" berths in the main cabin, above the settees on both sides. Its a great spot for
kids which combines privacy with easy supervision. In addition, there's a huge quarter berth and a huge vee cabin...and thats before you need to ask anyone to sleep on a settee in the main
saloon. Here's a random one from the
internet:

The mid 1970's S&S designed Nautor Swan 48 has these upper pilot berths as well. Plus it has an aft "owners cabin" with 2 quarter berths. I delivered this one across the atlantic:
