I only use a Lyman primer flash hole uniformer to make sure no debris are in the flash hole. I get more consistent primer seating depths if I clean the primer pockets but that's all. It's important for some auto loaders imo. It's not much more for your normal brass prep. While I may load on a progressive I prep brass by resizing, trimming, deburr, uniform, decrimp, and prime before loading. Makes it so much more streamlined and you don't waste case space with cleaning medium or liberal amounts of lube.
