Outer Wilds. It's a very unique game that's probably closer to reading a scifi book than playing the game, but it's beautiful with great plot, music, and puzzles. It's probably closest to Portal 2 on that list in that it's sort of a puzzley game and you need to be smart. It's very easy to spoil though so if you think you might play it I'd recommend just diving in.
It is single player so you'd have to take turns, but there's dialog that you could both read together.
