Which brand cable / type is best in for UK internal ethernet wiring

Looking at probably getting Cat6a and most likely going to buy a 300m roll, wanting to wire ethernet all over my house for linking up consoles, pc's and tv's
It will also be used to run PoE cameras and a few other items.

Going from ISP modem to a network switch then all these devices if that makes any difference. It will be running through walls both plasterboard and brick work in conduit and nearby electrical cables if that also matters.

Just wondering what's the best brand / version of the Cat6a cable is best to buy please.

any help and links appreciated thank you.
