Lots of opportunities for friendship in something like jiu jitsu. It's not for everyone, but it's interesting because it is a physically close sport, you get used to basically hugging everyone for a sport, it's both physically and intellectually hard to learn, and there's a common language around it. Easy to identify people at your skill level and meetup for open mats, share videos of techniques, etc.

There's a million examples of this out there, regardless of what you find interesting. Art, music, sport, working out, adventure, travel, computers, flying, whatever.

I find it baffling people keep talking about disappearing third spaces. There's so much opportunity to do interesting things with interesting people!

Paid classes of X never have been or ever will be third places. Because you have to pay a determinate amount to participate. One of the requisites for a place to be a _third_ place is you aren't obligated to spend money (or not a significant amount of it) to stay an amount of time where you can chat and make friends casually. That doesn't mean you can't make friends here but when we talk about third places we mean something else.
