The shouts of vendors in the street is why I avoid cities in Mexico, especially CDMX. The noise levels in Mexico are so abrasive to me.

No, I'm sure the biggest value of a gated community is the added safety. You'd still get the noises you mentioned, except perhaps the street vendors if the gated area is remote or big enough. It's still a residential area with parties, dogs, and delivery motorcycles, after all.
