2/5NL Crusher and I get into a quarrel...

hand:

2/5
fish limp HJ, Hero 30 Ks10s on BTN, SB 135, BB cold call, HJ fold, Hero call
(405) flop Qh8s9d
SB 105, BB call, Hero call
(720) turn 4s
SB x, BB 250, Hero flat, SB fold
(1220) river 8h
BB x, Hero 1.1k

Notes: BB is an older gentlemen, looks like he could've been in a band -esque. I did not know this but two regs told me afterwards he's a huge station. What are thoughts on river jam? Feel we have better flush combos (stuff unblocking AsKs, KsJs, 10s7s) to do it with but feels "pure" when checked to as we have air and BB showed weakness. My buddy said river jam is repping nothing as we'll always raise sets and J10 on turn, which got into an argument on turn play alone. So, what are your thoughts? Are we printing and getting AQ to fold with the turn jam while balancing our value (buddy's argument)? Or, are we instead blundering by stuffing the middle portion of our range, getting better to call and worse to fold, the converse of the fundamental rule for betting and avoiding a tricky node with potentially challenging river play with equities/math on our side (my argument)?
