2 week beginner here:

PF - 89s in UTG - without knowing anything about the table and how people have been playing, I would have folded here.

Flop: Danger cards are:
Ax, KK, QQ, JJ, Tx - pair
AT, A7, T7 - two pair
QT, JT - pair with backdoor straight draw
KQ, KJ, QJ - gutshot straight draw, high cards
XYc - flush draw

Now the blinds before you could have anything and their checking doesn't necesarily tell you much. MP3 and CO could have one of the danger hands.

8 outs gives you 5:1. Discount to 6 gives 7:1. Maybe discount to 5 gives 8:1. Pot odds are 7:1 so bet is marginal (other than for value). If a raise came behind you, pot odds drop to 4.5-5.5 to 1

Your bet did drive out MP3 and CO so they must not have had good hands. If you had checked, they may have checked as well or CO may have tried to bluff.

Turn: 4.5:1 pot odds are marginal for 8 outs - and if you hadn't bet the flop, it could have been 3.5:1.

Do you have any stats on the SB/BB players or impressions about how the table had been playing? Would like to know that information if possible to perhaps re-evaluate my thoughts.
