@happymomof1 has a great point about doing academic exchanges at the Quaker colleges https://www.college.upenn.edu/quaker-consortium. You can also take a break from Penn for a semester if you can find credits they will accept back from another school - maybe you could do a whole semester at Haverford? Can you manage study abroad? Breaks like that can make a bad fit palatable until you graduate.
I know Penn’s ways and I completely hear you about the club scene. Penn fosters that attitude and it’s extremely toxic - all relationships and community involvement become transactional. For Penn, being involved in community is only worthwhile if it improves one’s own marketability. It’s an institutional culture problem.
Since you are in the center of the city, the other option is to get involved off-campus, go out, do things separate from Penn.
