Thinking about getting back into gaming - recommendations?

Haven't played anything serious since like 2008 before the kids happened. Now that my oldest is in school during the day and my youngest naps for like 2 hours, I'm thinking about picking it back up as a hobby. Don't want anything too time-intensive but also don't want some mobile garbage. Used to love strategy games and RPGs. What are people playing these days that doesn't require a college degree to learn the controls? Gaming PC worth it or should I just grab a Switch?
