Sorry if this reply is too late, but Anna Dodson and I had great fun with https://www.nintendo.com/games/detail/good-job-switch/ which although not super long, was a good co-op game, and it's not too serious so you can have some fun with it. We recently got https://www.nintendo.com/games/detail/moving-out-switch/ but that needs a bit more work and isn't as "fun" of a game, as it requires a lot more coordination
