@illusionist there are several OSM based maps that will try to provide you with whatever language you like.
I think the Maptiler layer on osm.org will try to match your browser preference, the cycle and transport layers also display levels in English where possible.

The “default” iD editor has a field for this if you apply a road preset to a way.
