Hi & welcome to Gardenweb.

Most plants the local stores offer for full sun should do well, as long as they aren't known for being thirsty all the time. I love Bougainvillea vines, Dracaena marginata trees. Folks with experience in your intense sun would be best to advise, though.

FL is so different from everywhere else, with the unique climate and so many plants most of us have never heard of. You might find some good ideas by visiting the Florida forum too.

I'm from New Orleans which has some similarities to Florida climate. Tropicals like hibiscus, bouganvilla, mandevilla, ixora, and things like shrimp plant, lantana, calibrocha, herbs like salvia, veggies like tomatoes, peppers, dwarf okra, ornamental peppers are gorgeous. I would definitely use light colored containers if you can, mulch the top of the soil, and you will most likely have to water at least daily.
