I think all bet sizes, from neglectable to gargantuan find common practice in the game in appropriate situations

This is what a good NL player would say. Figure out your most +EV play and do it. Bet the most they will call incorrectly or bet more to get them off a hand that beats yours, or bet less to induce a raise, or make a bad call that they wouldn't have otherwise if you bet larger. Just balance some information hiding if you need to. There is no default bet size. I've been in many situations where I min-raise to push in overbet the pot 4x with many different hands. That's the art to the game.

Induce your opponents to make mistakes...
