Level of Detail

Level of detail - and choosing texture size for images.

4k textures  of course is only for things close to the camera.

So level of detail or LOD is an important consideration and really the first stage when taking on any modeling job or designing models.

First thing you ask is will this be in foreground middle ground or back ground

Foreground of course is 4k,  middle and back 2k or even just hd would be enough.

You can right click on view and render in an object properties tab and use a driver (using scripted Expressions value) that uses the camera distance to select the resolution. He uses the modifier limits to limit what resolution you want.  Awesome, for bigger scenes (and slower computers)

This is a tutorial for a plugin that uses lod.  He uses the decimate modifier to make 4 levels lod objects.  I imagine this still applies using geometry nodes.
