It could be broken down into a couple of further categories somewhere in the middle:
Where probes have landed - Venus, Moon, Mars, Titan, a couple of asteroids/comets.
Where probes have only flown past - Mercury, a few asteroids/comets, Jupiter and its’ main moons, Saturn and its’ moons (except Titan, see above), Uranus, Neptune, Pluto, Ultima Thule (now officially named 486958 Arrokoth).
EDIT: on further thought, there’s another one in between those two.
Where probes have orbited - Mercury, Venus, Moon, Mars, Jupiter, Saturn.
