As Landopope stated, it really does depend on varying situations. Mainly position, stack sizes and read on the table and villain.
I'd play AJ cautiously, especially in EP. If I ever feel I'm on a table where I can't play AJ early properly, I'll fold them out. Otherwise, standard raise in later positions.
AQ is a little more tricky, I'll play cautiously but I'm never folding unless there's a 4-bet in front of me. Play aggro and re-evaluate if I come across any resistance.
AK, I'm almost always 4-bet or 5-bet shoving unless I have a deep stack, 50+bb and I may lost over 60% of my stack.
