For faders, have you checked Fader controllers?
For pots I don’t think we have an equivalent topic. Just these days there is some discussion on E16 - Another new Oxi Controller?. There is also vivid conversation on Roto Control (MIDI controller by Melbourne Instruments). These are different approaches to have a bunch of pots at sight. Instead, you can reuse the same physical pots for multiple functions. Whether this is better than many more physical pots (taking much more space), that is subjective.
