I like how the games allow the ability to freely move in and out of my ship and the game worlds offer a good amount of exploration. And it might sound silly, but I like being able to perform maintenance on my ship.

Again, this is just my thoughts on it and might not give off the same feelings to others.

Outer Wilds has 6dof in your spaceship. It has modestly accurate spaceflight, though everything is on a tiny scale. You can fly from planets, into space, match velocities, etc. It’s a game about exploration and mystery without any combat, though.
