After the mildly stressful intro (which isn’t bad, just uses more sticks than carrots in the tutorial section), you basically just pick a direction and go.
If you wanna quest, there are quests available in (almost) every system.
If you wanna farm, pick a nice planet and get to building.
If you wanna fight, go find a planet with hostile Sentinel presence.
There’s always something interesting to do, but you can also just find a nice view on some planet, build a couch and just watch the iridescent grass blow in the wind for a bit.
