I agree UTM is used less and less as there are fewer maps in UTM (vs maps that used to be in UTM reprojected into Web Mercator). When using UTM, you can get awkwardness when the displayed portion crosses a zone boundary. It makes sense to decide the zone based on the center, and then convert all the rest of the screen to/from geodetic coordinates based on that single zone. This will result in some UTM coordinates with the wrong zone, basically extended from the next one, instead of the UTM coordinates you'd get from the geodetic coordinates, but it should still render ok. And if a UTM-style TMS-ish source has tiles in that beyond-the-edge region, it should work ok. I could well be misunderstanding.
