The best Ethernet cable for gaming is either a Cat-7 or Cat-8 cable with a gold-played RJ45 connection and enough length to reach from your modem or router to your gaming rig. Cat-7 cables should support enough bandwidth for gaming. But if you need more, a Cat-8 cable like the Smolink 10-foot Cat-8 cable* supports 40 Gbps transmission speeds. If durability is a concern, look for a nylon-braided cable, like this one from UGREEN.*  *Amazon.com price: $9.99 and $9.99 (as of 05/03/2023. at 3:46 pm MST). See full disclaimer.
