I would say start with hobby-based circles. Look for local events and meetups (concerts, games, hobby shop events, etc.) as a way to meet people.
If you happen to like TTRPGs, in my experience that’s a fast track to very close friendships that tend to have the deeper level of connection you’re describing. My guess is because TTRPGs require good communication, the comeraderie tends to come naturally faster than any other given group of people. It’s never a guarantee, but it’s certainly worth a try if you’re already into tabletop games or are curious to get into them
I hope you find excellent homies ASAP, wherever you find them :]
