According to standard strategy after the reraise QQ is a push having stack size:raise size 5:1.
I would do against unknown in first situation to get a read which with hands he reraised me in the case he calls, but for sure not feeling well and knowing that I could be behind against a reasonable player who does not respect my UTG raise from MP.
But often enough villain does it with hands like 99 - JJ but also with AK or AQ against which I'm in front preflop.
For sure we have some good FE preflop as UTG raiser (question to the judges how to "calculate" FE?)
Postflop is hard to play. We do not get a real additional information even on this flop. Villain can still hold his AA KK 99 which we have to be concerned about additional also 22 44 which is not to be expected but possible.
So we push here in a worse situation than preflop, so a push preflop only has advantages at this spot against the push postflop imo.
Point2:
Didn't understand your Flopplay for real.
If your ready to push against a raise
a) you can push preflop also 
b) You can play c/f even if your very deep in the pot - an absolute weak move for me.
The longer looking at this hand: A clear push preflop against unknown. You're using all advantages you have and if running against AA KK or villain hits his A or K let it be.
So I think that's the reason why standard strategy says "push"
So there was a lot to "evaluate" (not my job
) let's say to discuss in this hand 
And I made it clear to me why it should be standard to push here preflop
