if you only need 20gbps (so basically, you're not trying to run a bunch of 4k monitors over one cable) you can get passive 2m tb3 cables that, if certified, are probably higher quality than rando usbc cables, and I don't think that those would be likely to be more capable. Eg: https://www.amazon.com/Certified-Plugable-Thunderbolt-20Gbps...

If you want higher bandwidth and longer you can get active cables or optical ones, but those are obviously more expensive (it's better to think of them as their own electronic device than a cable).
