So what is the port speed of the device on the other end of your cable. If you plug it into a 1gbit port on your router the devices will negotiate it to 1gbit. Even if the router had a 10g port where is the data going to go. It is unlikely you internet is faster than 1gbit and unless you have another machine that can run 10gbit any file copies to that machine will also be limited to 1gbit. This assumes you have disk systems that can even exceed 1gbit.
What's your internet connection and router model? Mind you 10GbE transfers at a rate of 500MB/s, you'd need an SSD capable of that and router must also be 10GbE capable as well. Cat6 is fine for shorter runs of below 30m afaik. Cat6a is better for longer runs. Cat7/8 isn't needed.
