  Thunderbolt certification is mandatory, not optional as it is with USB, to be permitted to use the Thunderbolt logo on your connectors. The certified cables are listed here: https://www.thunderbolttechnology.net/products https://www.thunderbolttechnology.net/products (select Cables, then Thunderbolt 4 or similar)

      Thunderbolt 3 has to give up to 15 watts of power delivery on copper cables, anything beyond that is out of scope for the standard.
