In Total Commander / Bejond All Reason apparently good players spend most of the match in a very zoomed out tactical map.

In general I think the Total Commander genre is one of the few that allows a somewhat usable total view. Another good candidate would be Homeworld, since there microng is not that important so you can probably play a whole game on the starmap.

Other cheating answer would include… Very small old rts on modern screens. I think a smallsized AoE II map on original resolution would fit on 4k panel…
