Only one passing mention of martial arts so far? Consider Brazilian jiu-jitsu, which is certainly not safe but is very grounding. After spending all your waking hours at a computer, grappling presses your soul back into your body. It's a very different kind of socialising, mutually-exhausted extremely-physical and in my experience very wholesome, even if the injury risk is higher than nearly every other hobby. (And you guarantee getting every airborne infection. I got two serious colds and the bona-fide flu this winter; still worth it.)

What :D? I would say BJJ is an exceptionally safe martial art in that you can spar at 90-95% and not get hurt at all. Muay Thai or boxing sparring gives you regular bruises in comparison. At least that’s my experience.
I think rock-climbing fills a similar void for me. It's social, physical, and mental, and has a progression to it where I feel like I've gained something after every session. Plus you can take your skills outside and enjoy nature and travel with friends
Or try the other side of the spectrum and pick up tai chi. I started practicing almost 15 years ago (grudgingly) and it's surprisingly great!
Happy to help find a place that fits. In my experience, martial arts schools are very much a vibe-compatibility thing.
