Jam on the flop after the small blind bets $80 into a $210 pot.
This is a perfect opportunity to semi-bluff. You have 9 outs to the nut flush and 3 outs to top pair. The only hands that are going to be comfortable calling your all-in are a completed straight or combo draw. You'll get a fair amount of folds from overpairs/top pair in this spot and many good players will fold two-pair or a set here. And when those hands don't fold, you are still in fairly good shape against them.
Note that your 3 outs are likely devalued somewhat as an Ace coming down will likely give other players a better pair or two pair but not as much as you would think since, if you jam, you'll fold out hands such as AK/AQ/A9/A8.
So, when you combine the fair amount of fold equity you have here with your massive amount of equity in a multi-way pot it becomes a clear jam.
Many players will suggest the way you played it is best but I strongly disagree. If you call the small blinds $80 bet, you are obligated to call any all-ins from players yet to act (assuming reasonable stack sizes) simply because you are getting the correct odds to call — folding is far worse than calling in this spot.
Note that I'm not saying your line, as played, isn't profitable — it definitely is. But what many players don't consider is that you need to try and choose the line that maximizes expectation. There might be numerous lines you can take that will, in the long run, be +EV, but there is only one best option.
And that's really the most important point. By jamming over the small blind's $80 bet, you fold out a ton of hands that would have jammed themselves while still being in good shape if you do get called.
Any time you can achieve the same result playing aggressively as you can playing passively, you should always choose the more aggressive option (ignoring balance considerations) because you maximize your fold equity while also limiting your opponent's strategic options. By playing this hand passively, you give your opponents more strategic options. If you play it aggressively, you take away those strategic options while playing the hand just as, if not more, profitably.
