From what you say the area you want to sail
is from Baja to San Francisco so you must be a Left Coaster.I just reviewed the Feb. Lat.38 boats classified in the 28-31'' size.
There are some nice boats to choose from.
My suggestion since you have some sailing experience is to call the owners of any of the boats listed in your area and go see them and get a trial sail.for your purposes
the degrees of difference will be finite!!
Cost,condition,and how it sails will be more important,then say, will she round the horn
