Not sure how to play this preflop shorthanded, specially from the SB.
Considering that utg is mp2 on FR, I think I'd only cold call here, if I was sure that the BB was a passive or a nitish player and if I had other fishes involved in the hand (anyone that would call me if I hit my set).
Otherwise, I'd simply squeeze or fold, based on the mp2 and mp3 stats, because we don't have position here and we will hardly close the action otf.
So, against good opponents, It'd be very hard to continue the flop, when we miss our set, even in dry boards and our pair loses a lot of equity against 2+ opponents.
As played, I would've donked the flop as well (wet board and we are oop against 3 opponents). I usually play more straight forward, when I'm oop. Maybe bet a little bit more otf.
OTT, I'd bet/fold 1/2 pot and check/fold or bet small/fold, OTR unimproved.
