Colour me noob but here's my thoughts.

Play low pocket pairs strictly fit or fold for set value. Check/fold the flop if you miss your set. If (like me) you tend to cbet way too much, this will also reduce your cbet% stat which can be helpful for your image.

Extracting any value from a low pocket pair that has missed the flop is an advanced play and requires good reads to be profitable. If you are not absolutely certain you can play it for a profit in this situation against the current opponent(s) you need to check/fold.

I think when people advocate folding 22-66 PF UTG it's because beginners especially tend to get married to their hand and overplay weak/missed pocket pairs. If you have the discipline to check/fold missed flops it's profitable to play them (assuming proper stack sizes for implied odds on your callers).
