Copper's loss tangent is high. There's no getting around that. PAM4-based 50GBASE-CR DACs have similar length.
Twinax has more bandwidth than STP. We're at the physical medium's limits. Sure, you can pump the voltage but that quickly hits diminishing returns. Best to use copper for sub 1 meter and fiber otherwise.
