Center Cockpit boats built to cross oceans do not include any on your list...though the ones on your list can get you to the Caribe in coastal hops.
Hylas, Passport, Caliber47, Tayana42/47, KellyPeterson44, Brewer 42/44, Bristol 43/47, Hans Christian Christina are some you might look at. There are also a number of older expensive boats you might look at depending on your budget...Hinckley, Little Harbor, Shannon, HR, Oyster.
EDIT: I should further qualify...Tartan makes an excellent boat but I am not aware of CC's except from the 70's. The current 4400 and 5100 are DEck Salon models and have exposed spade rudders which I am not a fan of for ocean cruising.
