I would use 231 to Dothan Al, then pick up US 84 and follow it east to US 19 in Thomasville Ga. then go south. Pick up 98/27/19. 27 to Ocala, then 441 south from there. When you get close to Orlando, you're on your own. :)
All good roads, with only the occasional small town to deal with.
Spent most of my life in Fl and can say with certainty that I-10 and I-75 can be incredibly dangerous, frustrating and often bumper to bumper, so I don't mind taking the scenic route and the extra time to avoid them as much as possible.
Most of the side roads I mentioned are 60-65 mph speed limit, which often can be faster than I-75/10.
Only drawback is gas stations can be sparse, so plan accordingly.
Sorry for the multiple edits....
