At the end of the day, you should ask your instructor, but Light Monkey 200' reel is my go to for 95% of the stuff out there. It'll get you through a cavern class and work for the majority of cave diving you'll do if you're diving in North Florida.
The longest run you'll probably need to make in a cave class is upper Orange Grove, or if your instructor makes you, either sign at P1. There's plenty of line on the LM 200 reel to get you there.
If you feel the need to go to a bigger reel, the LM400, Halcyon Pathfinder 400' reel, Divesoft 100m reel (even though I'm not a fan of the line they pack on it), and Dive Rite sidewinder (NOT the slide lock) reels are fine.
