You will get a lot of stiffness in at least two ways: form stability and a large righting moment.

Form stability requires a wide flat bottom. Luckily for you, most modern production monohulls have exactly this. Especially the shoal draft boats.

A large righting moment a low heel angles would come from a canting keel, water ballast, or a deep keel with a heavy weight on the end. Probably none of these are that practical for you.

With a modern flat bottom boat, I would think you could quite easily stay at < 12% in most cruising situations with a little practice.

I would look for a boat with flat aft sections and a high ballast/weight ratio.
There ya go! Late model Class 40 or IMOCA 60. Awesome form stability, ballast ratios over 40%, outboard water ballast tanks, and deep-reefing ability to depower in thunderstorms ... or the Southern Ocean. And the canting keel makes them perfect for Florida's skinny waters! Might have trouble meeting the budget, tho.
