Outer Wilds, 100%. It might be missing the mark a little bit by the end, but it never demands anything more than your curiosity to discover. More than likely, it will make you want to explore every nook and cranny.
And definitely go in completely blind and enjoy the story.
Ninja edit: Outer Wilds is absolutely phenomenal, my comment about it missing the mark is purely based on you looking for a chill game. It is very chill all the way through, until you really start digging in and it wants you to explore everything.
If you'd like to try and find a faster way to alienate a neurodivergent person, this is basically it.
My parents still have no clue how to regulate there comments when I mention my difficulties. They love pointing out how "pretty much everyone struggles with getting their real life taken care of."
Yeah, and I'm sure everyone else also sits there for hours at a time, lamenting themselves for not being able to get up and getting it done. It's less about the inability to get started, and more about the excruciating guilt you feel when simple tasks take hours of internal bargaining to finally get done.
