Is there any benefits to joining a business frat after you wrapped up recruiting?

Hello guys, rising junior who has wrapped up recruiting for sophomore and junior internships (hopefully I get a return offer from my junior summer internship). I go to a non-target school but secured internships that we could consider “better” than what the avg finance student at my college gets.

Will I benefit in any way from getting into the business frats (DSP and those kind of orgs) because of the network or not so much? Like, is it worth it to go through pledging and get involved during my junior-senior year?

Also, do you actually make friends at those frats or is it just purely professional development? I guess if I don’t benefit career-wise but still meet good people that will be working in NY when we graduate its still worth it.
