Generic term for CRS axes?

We're making a light web front to a database, and I saw this in a test screenshot:

Despite those coordinates being nowhere near North America, the "latitude/longitude" label for those coordinates really ruffled my jimmies. This got me wondering if there is a generic yet unambiguous term for each axis.

The first idea that came up was to just change the labels to X and Y Easting and Northing, but my understanding is those are terms used specifically for Cartesian coordinates. If the CRS was 4269, then the labels we have now would be correct.

We can probably derive the proper axes labels from the CRS, but I thought I'd ask if there's an accepted generic term (other than "value that increments along the north axis") to just sidestep the issue.
