If your laptop is thunderbolt 4 and you're fine shelling out the big bucks on a nice dock you can get some really good hardware. I bought the thinkpad thunderbolt 4 dock and it's worked flawlessly for me for the year I've owned it. There's no real set line between whats a hub and whats a dock with USB C. Docks tend to be bigger and have more ports, while hubs are more portable but less capable.

Most cheap USB hubs can accomplish what you want, but they tend to be not as capable or reliable. Something like this gives you two displayports, some USB ports, and an ethernet for $70 which is pretty good if it's actually thunderbolt. Or there's even this which is just two Displayports.

I'd personally avoid any hubs with HDMI on them. In my experience the displayport to HDMI converters in them tend to not be cooled properly and die very quickly. Displayport doesn't require conversion so that's less stuff to fail. At work we've gone through probably 20+ dongles, and so far the basic displayport only + a few USB 2.0 adapters work the best.

Something like this in theory should be good enough. It has two displayports so you could just ignore the HDMI and hopefully it lasts.

Also if you care, some technical info on why almost all USB C hubs suck: https://overengineer.dev/blog/2021/04/25/usb-c-hub-madness.html The tl;dr is they're all the same for the most part, so just buy the cheap junk if you're going for a hub.
