I'm network engineer and I do not recommend this.
A UTP5e cable is more than enough and a lot cheaper. Indeed, the UTP6a serves only to spend 10Gb / s, the UTP5e much cheaper is limited to 1Gb / s.
Our boxes will not yet as fast (max also still very rare is 400Mb / s or 0.4Gb / s so we margin).
Same for our network cards, they are limited to 1Gb / s as UTP5e. A network card 10Gb / s it's rare and it costs 300. In other words, you do not have.
Flee this product, the seller flee, flee Chronopost.
