USB is still (as far as I know) a mess and that sucks.
But DisplayPort has great optical cables available! I was early in & they were very cheap then (no one trusted them yet), 50m v1.4 for $60. Turns out to be vastly longer than I needed, & got a 20m cable for gaming from the roof. There's even DP 2.1 cables now.
A USB4 with optical transport would be divine.
