how do you make friends if large gatherings arent your thing?

I do like large gatherings, but I don't really do well meeting people and making friends in them. I find it too chaotic and difficult to "be myself" with so many people. I also feel there tends to be more shallow conversation in these settings making it great for banter and social energy but less great for connecting and getting to know new folks.

I am looking to meet new people to be friends, as in capital F friend, not just a random person I know. Someone who wants to hit me up and go do something fun, check in on me and see how I'm doing, etc.

How do you go about meeting people and finding social settings that foster deeper connections?
