You don't mention the size of the blinds. If this is a typical Party SNG, the blinds are usually huge (200/400 and up) by the time you hit heads up. With blinds of this size you shouldnt be "firing a pot size bet" after the flop because there should never be a flop - if you raise preflop, it's allin. I agree with the auto-raise if SB limps except that you shouldn't do it three times in a row as they tend to start limping good hands after the second time you do it.

Any A or K, suited connectors isn't hyper aggressive in these situations. Hyper aggressive is raising every hand (although you shouldnt go that far). You should raise everything all the way down to hands like 96s. Be aware that heads up, a hand like J7s is far superior to something like 65s.
