Hi Kimberly, and welcome to NGA!
From what I hear, Florida has sand, fungus, mold, ravenous bugs, high humidity and high heat.
I wouldn't know where to start except for buying some water-holding additions to improve the soil in raised beds. I would start by adding bark fines plus anything organic I could get my hands on for cheap! But the best soil amendments might depend on what attracts the fewest bugs and soil diseases.
I bet one key factor in selecting varieties is disease resistance and bug tolerance. And resistance to heat and humidity. I don't think most tomato varieties will flower above 85F or so. Maybe you could grow "summer lettuce" in your fall and winter.
Is there ANY way you can grow "cool season crops", without air-conditioning your garden?

Here's one EDIS publication that has a big list of vegetable varieties that do well in Florida:

If you don't get many good answers here after a week or two, I'd suggest moving this thread to the Florida forum so more people will see it who know the answers. You can use the "Suggest a Change" button at the bottom of the thread.
I hope you get some people in this forum who know Florida!
You might also want to browse the NGA Florida forum and look for relevant threads there:
https://garden.org/forums/view...
Hmm, this next thread ought to provide some ideas! And since it has 110 replies, there must be a lot of people who have bookmarked it. If you read the thread and then ask a question THERE, perhaps being specific about what kinds of things you like to EAT, and what part of Florida you're in, you'll get faster answers.
The thread "Who grows vegetables and fruit in Florida" in
Florida Gardening forum
Or start a brand-new thread over there.

You can also search the NGA Memberlist for people who live near you put their approximate address into their NGA Profile. For example, I see around 12 people within 20 miles of Pensacola:

There is also a "Member Map" that shows the location of each NGA member who put their approximate address into their NGA Profile:
https://garden.org/users/membe...
(Until you zoom way in, the Florida map is wall-to-wall NGA members.)
It's nice to know gardeners near you, so you can swap seedlings, plant divisions, cuttings and experiences.

The local "agricultural extension offices" are usually good sources of local info.
