In your specific example, I don't think an A2s is enough to jam especially if there is another tight player you have pegged for an A2.

I'd want at the minimum something like A23 suited to ace, or A245, AA24. Hands like that.

It does add to fluctuations but all 'good bets' usually do.

I try to maximize my pot equity advantage on all streets. Gergery is right that future streets should be a consideration. But if anything I think a raise will help tie on other players to their hands and then they draw to non nut flushes and lows. It will also make it more correct (and possibly cheaper) for you to draw to a few backdoor targets on the flop.
