Any Advice on making friends irl?

Liiiterally anything at all, I have a car now but still no job 💔 I mostly struggle with talking to strangers and hoping it turns into a real friendship, what are real conversation starters instead of "how are you?" because that can get stale so fast. My town isn't that great tbh, there's a lot of old people (which is fine but I'd rather befriend someone my own age!!) and you have to pay to get into a lot of places around here which is insane. I do love the park but no one really goes there except old people. 

I also don't know how to deal with meeting someone I don't like based off the things they say, I don't want to ghost people but I don't know how to gracefully say "I don't vibe with you srrrryyyyy" IN PERSON.

I wish dan still did internet support group 😞
