At a full table I'll only play ATo on the button (unraised with limpers).
AJ is a raise in LP (sometimes) and a fold to a raise, and a limp (usually) in EP. I'll fold AJ more often than not in a MTT when the blinds are big and pre-flop action is more of the game.
AQ is a good hand to mix it up with pre-flop (limping for big hand value and raising for steals and to isolate) though a big raise pre-flop can make it difficult to laydown postflop.
The strength of AQ AJ and AT is in their big hand value in straights and two-pair more than their TPTK value which can cause huge trouble when they meet resistance.
I think it's more about knowing when to lay them down on the flop than when to raise them pre-flop.
