We have enjoyed Tomoka, though it is not our favorite. Mostly dirt roads with lots of humps and shallows on narrow campground roads. Some low limbs, too. Not big rig friendly. There is one pull through, probably easiest spot for larger rigs, but only 30 amp and ada site. Many campsites are shady. Quietier during week, lots of families on weekends. Beach access across bridge in Ormond Beach, maybe 15 minutes. Short drive to many stores and reastaurants. Bathrooms clean during our visits. Rangers have treated us well.
If you really want to be near the beach, check Gamble Rogers SRA a bit further north. It is likely booked every weekend, but watch like a hawk for cancellations. Really nice.
