'niche' gym recommendations - community/welcoming vibes

I live in the summit hill area and would like to join a gym that has a community feel to it. For reference, I'm 25F and have played a variety of sports growing up and in college. Particularly enjoyed rugby, rowing, and flag football. I'm intrigued by things like cross fit, power lifting, jiu jitsu, etc. Kind of looking for 'unique/niche' activities. Just looking for something new to try and get me going again... thanks!!!
