Nauvis - main base is fully enclosed with walls, flamethrower and gun turrets. Before this I’ve definitely set up a mall, nuclear, and roboport coverage.

Any planet - I want a ship for myself and ad hoc requests that can definitely get to and from Nauvis without supervision.

I’m playing the current save relatively chill, so I’m moving off secondary planets when that planet’s science setup is self-sustaining, and Ive got most the research I want from there.

Between the first two requirements I can drop myself and what I think I want to a planet, send the ship to Nauvis or other, mess around a bit, and request some more resources from the ship when I realise what I’m missing.

Ive done vulcanus and fulgora and am starting gleba, for reference.

Taking it chill includes side quests like supplying a stupidly big artillery battery on Nauvis.

Kinda true. You’ll want good defenses in place with bots set to repair before you head out, but there’s also nothing stopping you from shipping all of the components to build another rocket silo on the other planet as soon as you drop.
