I don't quite understand your reservations on what you refer to as deep draft. A draft of 6 1/2' can go anywhere, with the possible exception of some of the Bahamas. Generally a boat with deeper draft is better to windward.
Boats of all drafts can hit bottom. Owners of shallow draft boats may be worse off as they can be a bit more adventurous.
CS33 and CS36T are both great boats, and roomier than others you are looking at. For example the CS36T is over 2' wider than the Spencer 35 which can be a bit tight below. The Yamaha looks pretty good as well - I would not worry about the draft.
I would forget the Westerly. A center cockpit 32' without a passageway to the aft cabin is like a 26' boat inside.
36' is not hard to handle - the bow is just a bit farther away.
