Probably would be helpful if we knew a little more about the types of things or activities you like to do - shopping/outside activities/theme parks/state parks/ etc.
As far as beaches, you are essentially in the center of a state that is 150 miles wide, so within a couple hrs you can be at beaches on either east or west coast. East coast, Daytona is a good choice - you can drive on the beach and spend time watching people who don't know have any offroad skills get stuck in packed sand :) A little further south, Ron John's surf shop is iconic/interesting if you want to see a Bass Pro Shop's environment centered around surfing and water activities. If you want to drive a little further, Clearwater Beach is world famous and typically rated very highly in US beaches. There is definitely a difference in the environments between the two sides, with the Guld side typically having clearer water, shallower, warmer and shallower waves. The "beaches" on the west coast tend to get better as you go south from Tampa/Clwtr. North of there it is less - "beachy" and WAY less populated until you get up into the panhandle of Destin/Pensacola, but that is a 5+ hr drive from Ocala.
Sticking with water activities, Cedar Key is relatively close and a quaint/historic fishing village. They have a pier and a lot of art/craft sellers as well as historic homes. You can rent golf carts and drive on the streets. Another option would be Crystal River and swimming with manatees. February is a prime time for them to be up in the relatively warmer (~ 70F) water of the springs. There are a lot of tours that do this, I would recommend Birds Underwater as one of the best. There are also lots of pretty springs and state parks in Central FL - Salt Springs, Juniper Springs, Manatee Springs, etc.
Don Garlits museum is a great choice if you are into cars/drag racing. There is an offroad park in Ocala (Hardrock) that is the closest thing in FL you can get to real "wheeling" as it is in an old lime
rock mining area. It is not real big (~ 70 acres) and has a mix of easy/hard, but probably not something you would want to take a stock rental Jeep because of the small size and limited "stock" trails. There are limited areas for offorading. Ocala National Forest has a lot of forest roads, mostly sand and flat that you can do in a 2WD drive vehicle although there are areas with deeper sugar sand. South of there you have Citrus and Croom, which are again forest roads that don't require any hard core 4WD.
If you want theme parks, Orlando is not far away with a multitude of choices. Be aware that although they are open, right now you have to make appointments due to COVID, so you can't just show up at the door.
Hope that helps
