Shotgun bores and my ML are the only ones that get a hard scrubbing periodically. The former from plastic wads and the latter from plastic sabots.I guess cleaning means different things to different people. I don’t mind but I try not to stress over it.
For any modern semi auto pistol or rifle, for me it’s a wipe down and lube. Basically a shotgun sized patch with a little CLP to wipe the rails and other surfaces on a handgun for example. Maybe a nylon toothbrush at times around the extractor. Then lube. I have used a patchworm for years and pull a patch with CLP through the barrel and then a dry one. No rod or brush for the barrel.
For a revolver, I use a brass chamber brush chucked in a drill at low speed if after shooting say .38 special out of a .357. Maybe a little more nylon brushing around various parts. I’ll pull a Lewis lead remover through the barrel every now and then when I think it’s needed.
The only guns I’m a little more meticulous about are the blued steel and walnut ones. And that just means making sure to lube/protect the finish.
I highly recommend people at least try Wipe-Out on their bore if you really think it needs cleaning. Between a patch pulled through with CLP for regular maintenance and Wipe-Out on a crusty or copper fowled bore, I can’t even remember the last time I used a rod and brush in a bore. A leaded revolver barrel aside. Oh and also on shotgun barrels.
