The top part of your polarized range should be strictly for value. So if you want to include AQo in it, you should be willing to 5-bet/shove if he 4-bets. Otherwise, your 3-bet is a bluff and you might as well be doing it with 93o.
If your hand is not good enough to 5-bet/shove, but still playable against villain's open, then flat call.
Now think about the range of hands that are not good enough to flat call. The very top of this range should be 3-bet as bluffs. If Q9s is the weakest hand you are willing to flat with, then 3-bet Q8s. Add as many hands as you feel you can get away with, but start from the top down.
If you think the opponent has more of a tendency to call 3-bets, then your range should be depolarized. Just 3-bet strong hands for value and don't include any bluffs.
