I made a similar thread of Soothing Games 
- there are some recommendations in there. I too like to play a game before bed, and I think maybe the use case is slightly different. 
I think stuff like Stardew Valley, Harvest Moon, or Animal Crossing would be a good choice with the caveat that you might get pulled into “one more day” or “one more task” sort of mentality.
I personally find grinding in turn-based RPGs to be a cozy way to settle down for the night, I’d also recommend something like an Octopath (which is voice acted so you can close your eyes during cutscenes)
