For a modern RCA analog interconnect system, only two things matter.
1] The effectiveness of the shield to interference (shield needs to be connected at both end for best high RFI shielding).
2] Low end-to-end resistance.
Note that phono cartridge to pre-amp, microphone, musical instrument, digital and vacuum tube interconnects may have other requirements.

Note Two: a modern RCA analog interconnect system has a low output impedance and a high input impedance.
Some budget receivers, some battery powered units and some USB powered units may not fit that definition.
