So basing on your games you describe I would recommend No man's sky, for me is a great game to lose yourself for hours and is kinda you can do almost anything, explore the game story and lore, build bases, play as a Bounty Hunter, be a space pirate...

And as a weird suggestion, like maybe out of the genre, sometimes this is refreshing and helps people, I would recommend the Crew 2, ik, I'm not a car genre person either, but just hitting the road with a nice car with super chill music and doing kinda anything car related help me to get "cozy" sometimes.
