Turn-based RPGs generally move at the speed you do, so they aren’t intense in a way you’d have to worry about, and there are a LOT of them. Many Dragon Warrior, Final Fantasy, etc. games.

What I call ‘procedural’ games would also work, things where it’s less about pushing yourself to have perfect reaction times or compute complex values in your head, and more about just walking through the process in search of the Zen of flow state. Lots of simulator games fit in the category: train station renovator sim, house flipper sim, power wash sim, rover mechanic sim, mech mechanic sim, etc. Hardspace: Shipbreaker is a favorite in this category. There are also games like ‘Papers, Please’, ‘Contraband Police,’ etc. where you run down a checklist and try to spot anomalies.

Life games serve as well. They usually don’t have a hard limit on how you play through them so you can play as you like and progress in whatever way. Stardew Valley, Staxel, the My Time At … series, Farming Sim, etc. all lean toward just being pleasant rather than an intense challenge.
