> Fiber is cheap enough too if you want some 10Gb devices.

The problem with Fiber for now will remain that so few consumer devices can actually connect to it without first converting to RJ45. You are p much limited to some enthusiast networking gear and server gear and everything else needs you to convert.

I recently had my families home ethernet situation upgraded and we went with Cat8 for now (it wasn't meaningfully more expensive to doing any other Cat cable all things considered). It is compatibile with networking stuff that is commonly available today and hopefully in the future some switch will appear to make full use of it (I am slightly sceptical, but I assume 10G will at least still be seen over Cat for consumers).
