I grow rosemary which makes a great shrub and provides a wonderful fragrance and available spice. I grow basil which does really well, also oregano. Do not try mint except in a pot. It will take over. One small plant and you can't make enough mojitos or mint tea to use even a small % of it. I tried with the mojitos and failed badly.
There are lots of plants and shrubs that used to do great but have not survived well the past couple years. Those that die are getting replaced with things that thrive.
There are several good books on Florida plant and shrubs available that will help.
