Another option is horde shooters. I dove hard into Vampire Survivors when I was dealing with some issues at work - short play sessions, real feeling of progression and unlocks. Levels can be a little stressful, but the cost of dying is so small. See also, Brotato, 20 Minutes til Dawn. All great games.

This post is a bit old now so you probably made a decision but I loved A Short Hike. I went in with a lot of hype and still really enjoyed it. It’s simple but plays very well and is over quick (I find completing something is satisfying when I’m stressed). Good luck and be well.
