Many laptops can't handle more than USB 2.0 when outputting display over the same port. Those that can need a certain protocol (too lazy to look up). There's a better protocol that allows both, but now you're in the $100+ range of hub/docks that can handle it.

You are thinking about USB-C Alt Mode, which is a way for displayport to go over USB-C.

To get 4k60 + USB3.1, you either need USB-C Alt Mode with DP1.4+ (supported by almost zero monitors), or Thunderbolt-3 (supported by fantastically expensive monitors).

It's much more economical to live with USB2.0 for your keyboards and mice, and get a separate USB3.1 hub if you need that.

Thank you.

I was originally hoping to have gigabit Ethernet on the same monitor hub, but settled on the 300mbps actual throughout USB 2.0 allowed. At least it provides reliable low latency.

Apple multiport dock supports 4k/60 hdmi and usb 3.0 somehow, but only on 2019 and newer macbook and ipad models.

I'd guess that this might be related to USB A (2.0) being only rated for 2.5 W (up to 7.5 W for the "Battery Charging" specification), while USB C needs to support at least 15 W (up to 240 W) ?

That would be Thunderbolt 3 or 4, I guess?
