How often you can coldcall also depends on the BB. If BB squeezes a lot calling will be less attractive.

With the hands you listed I wouldn't ALWAYS do one thing. If you always 3bet small pp's from the sb and never flatcall with them your checkraises on low flops aren't going to be believable versus thinking players you have history with.

If villain is calling your 3bets very often and shoves over your cbets lightly then folding the low pp's is probably best.

Of the hands you listed I'd be most inclined to 3bet the pp's and JTs and most inclined to fold A6s.

With 100BB stacks 3betting KQo is fine too but with deeper stacks it plays pretty bad oop in a 3bet pot so calling is often better then imo.
