I'm currently gathering parts for a 9mm upper and I'm at the point that I need to decide on a buffer. I'm using a Macon 5" barrel and plan on leaving my silencerco hybrid on it 100% of the time. I've read people saying heavy buffer/heavy spring, heavy buffer/light spring, hydraulic buffer/light spring, or captured recoil assembly. What's my best option to not make my 9mm upper beat itself to death?

Definitely heavy 9mm buffer (a tad longer than regular).  Maybe extra power spring, maybe regular spring.  But springs are cheap, and you probably already have at least one regular power spring.  

May also depend on your bolt choice (most 9mm bolts have extra weights) and whether you want a standard type buffer/spring combo or one of the captured (JP, Armaspec, etc)

I run a JP .308 carbine spring and a hydraulic buffer in my Colt mag gun and the recoil is sweet." />

I use a 9mm JPSCS from Maxim Defense and run a MiniBoss on the 3lug full time.
