USB 4 is essentially Thunderbolt 3. It transports either USB 3(.2), PCIe, or DisplayPort in one of two variants.
Support for these features is still mostly optional. The only real upgrade is that -- as far as I can tell -- USB4 requires host devices to support DisplayPort. It's still a USB-C connector, so I don't see the cabling situation improving.
