I understand that '1:50,000' etc is the cartographic tradition, and geographers routinely infer resolution from this ('what is the distance on the ground of the thickness of a pencil line on the map?'). But a length measure is more direct and less ambiguous, and also applies to gridded data.

I would also prefer to have one solution that fits all use cases, but we should also recognise that this two ways of expressing spatial resolution (i.e., distance and equivalent scale) are not comparable or convertable. So, IMO, the use of two different properties is more than acceptable.
BTW, my request is based also on an explicit requirement from GeoDCAT-AP - which is defining mappings from ISO 19115:2003, where spatial resolution is expressed either as distance or equivalent scale.
