Working in Thun, Where to live (Bern, thunder, maybe Interlaken)

I'm moving to Switzerland and will be working in Thun. Trying my best to figure out where to live. Would anyone with experience with these places recommend Thun itself, Bern, or maybe even Interlaken? for context. Im a 31yo young professional. I'm mostly looking for a peaceful life, but Id love the option to have some fun once in awhile and the option of different activities to do. While not facing too difficult a commute to work.
