Decent cable is already made to a very tight tolerance of 100±5 Ohms, testing this accurately at RF is a challenge. It turns out that much of the impedance irregularities come from badly assembled connectors where the twists have been opened out too far from the pins.
Ethernet cable has always used solid cores in installed cable, using stranded cables for the patch cables, where flexibility is essential
We avoid silver plating at RF because it can only be used in a sealed environment, the black sulphide that quickly forms in city air is a poor conductor
There is a lot of information in this brochure:
