My vote went to asteroids (though I think space in general fits). I think after awhile, that planets will only be settled to set up initial infrastructure on the planet. Many people will probably stay, because they've built a life already. And instead of vast surface colonies, you have concentrated cities, with most of the population in Dyson bubbles around the planet, built from planetary resources and nearby asteroids.

Well, I voted for Ceres/Jupiter/Saturn. Not just because of what Elon has said, but because a surface colony can pretty much grow indefinitely while a cylinder is limited my the tensile strength of it's material. And Venus if currently a bit "off-limits" as the Dv required to travel from a floating city into LVO is beyond Starship's Delta-V capacity.

In particular I have a bit of a soft spot for Titan, since it's the best source of Methane beyond Mars and that's what Starship runs on. Of course, if Roscosmos or the CNSA builds a similar type of vessel using Hydrolox or Hydrogen NTR propulsion, that changes a lot.
