Some places I have found to be good, and indeed worth your time:
West Coast
Fort Desoto Park near Tampa is Epic! The North Lagoon at the end of the road in the North West Corner is the best spot. Go there. Also, Ding Darling is acceptable, but not great unless you are there for low tide. Bunche Beach can have a lot of birds, yet not always. Sunrise or sunset is best. Skip Corkscrew, unless you really like warblers.
South:
You must drive through Loop Road, off Tamiami trail. There are a lot of gators there, and many many birds. I saw a Great White Heron when I was there last week! Also many Night Herons, and even a Florida Black Bear! Shark Valley in a Morning only place, try the canal to the right of the buildings once inside.
Everglades National Park Main Entrance: Try Flamingo's Eco Pond, but be there before sunrise. When I was there about two weeks ago, there were over 100 snowy egrets landing about half an hour before sunrise. The best action usually happens before the sun rises, though plenty will happen in the hour following.They fly away and roost, but will intermitantly land and refeed. Mrazek Pond will be great, maybe. Paurotis Pond will have nesting Wood Storks, How long is your glass? You can still at times catch flyovers. Anhinga trail is good, but more in the afternoon, I find. Here is a great website link for information:
http://photo.net/learn/nature/everglades It is old, yet I can attest still true. Totally do a sunset at Pine Glades Lake; you will remember it forever! (unless you get clouded out, unlikely this time of year).
East:
Wakodahatchee Wetlands in Palm Beach County has nesting Wood Storks, Great White Egrets, and Great Blue Herons. The heron chicks are beginning to fledge. Green Cay is good too, Loxahatchee I would likely skip. Elsewheres north on the East Coast I may say no more, having not been much else where, except Riverben Park, which is pretty good too.
For general advice, I would say spend your time seeking what you can find only here. The Spoonbills are lifechangingly dramatic, if you can find them! Seek at Eco Pond before Sunrise, or hike the Christian Point Trail, if it is wet, or, look in the pools behind Eco Pond )the trail by the sign; you will know it when you find it).
