Cat6a Câble Ethernet en Vrac, 1000ft (305m), 23AWG Fil de Cuivre Pur Nu Solide, 750MHz, Blindé (S/FTP), PVC CMR (Bleu)

This seems to be pretty decent quality Cat6a riser cable with a PVC jacket. The plastic pair separator is of adequate size, the wires seem to have the correct twist, and the PVC jacket actually seems to be a bit tougher and smoother than average. I also did a scrape test on the wires themselves and they are definitely solid copper rather than CCA. The pull box is also sturdy and I had no trouble feeding a bit of wire from it. I would think it should work quite nicely for any basic 1Gb/2.5G/5G/10G wiring job.

High quality SFTP cable. Not too tough to bend, but notably more sturdy than non insulated products.

This is excellent cable. Each conductor is 23AWG, which means it's very thick and it's solid copper. That means you are going to have no issues getting 1G or even 10G speeds on it. It's shielded so you can run it next to power cables if you need to. You can only terminate it with a shielded keystone jack made for it or a shielded patch panel.
