That can be solved the same way it was solved for SD / CFe cards. Just have a single mark which guarantees a baseline set of requirements.

- "USB Speed 2" means [20gbps, thunderbolt 3, displayport, 20 watts].

- "USB Speed 3" means 100gbps, thunderbolt 4, etc.

- "Power 100" means 100 watts minimum.

Make a little logo for each standard - "S2" / "S3" / "P100" which can be branded onto each end of the cable. People who care can look at the logos and tell what a given cable can do.
