Just about anything you want depending on your microclimate. I have mango, lychee, jaboticaba, canistel, mamey, tamarind, achachairu, atemoya, Rollinia, sapodilla, and just about everything else. Even experimenting with breadfruit and some other ultra tropicals in very protected locations. The further away from the ocean the less you can grow.
Also north of the river and east of the interstate tend to be colder. Cape Coral is a nice place to grow, but you can't as much due to city restrictions. Pine island is a great place to grow. Anything south of the city limits of Ft Myers is good.
