It doesn't feel like either an interesting use of the world or a good story to me to have Superman spend lots and lots of time going after low powered villains who have no defense against his super speed, super brain, or super vision. It does feel like a good panel or two to have happen now and then though (usually while something else is happening in the thought balloons or conversation with someone else). Similarly for James Bond going after small time hoods.
the "experienced operative vs gangs" is a repeat trope. Pretty sure that's the plot of Denzel Washington's new movie. Probably a 33% chance it applies to any random western. Wouldn't surprise me if there isnt at least one arc in the Odyssey that would qualify.
It is undeniable that Superman stopping superman-level threats is the most useful thing Superman could do. But I would posit that if Superman spent 5% of his "hero" time nabbing career criminals that would require >SWAT effort to capture but that are way below his grade, he would have a outsized impact on crime.
