I wouldn't recommend having one standard way of playing any hand.
Important considerations include depth of stacks, blinds, blind structure, # of players in the pot, other player's or players' tendencies, pre-flop action, position, pot size....
A paired flop is unlikely to hit your single opponent and make trips - but think about what they would have called your (presumed) preflop raise with. If it comes KK4 that will hit a lot of hands that call you (AK, KQ, KJ depending on how loose your opponents are). If it comes 33J I would be much less worried.
Getting it all in preflop is reasonable with AA but after the flop you only have top pair so don't go wild unless you're already committed. Hopefully you are in position and can see what your opponent(s) do before you have to act.
