I don't know why you're getting downvoted, this is a very good question that makes no sense at first.
USB-C is a complex standard, but basically, just because your connector is USB-C, doesn't guarantee what can actually go over those wires. First you have to have the connector; then your device needs to have a chipset that is capable of specific processing and protocols; and then it needs to actually implement those protocols with other things on the device. So your USB-C connector might only support USB 2.0, or 3.0, or 3.1, or 3.2, or 3.2 Gen1x2, or 3.2 Gen2x1, or 3.2 Gen2x2, and possibly PowerDelivery, and possibly video, and possibly audio, and possibly mass storage, and possibly ethernet, and possibly basically whatever feature you want.
So you have to actually look up the specs of the device you have to find out what it will actually allow you to do over that USB-C cable. I bought a USB-C phone years ago only to find out it supported virtually nothing besides USB 3.0 file transfers, and a dumb charging standard proprietary to that one vendor.
Samsung Galaxy phones do a ton of stuff over USB-C, including video out, and even DeX, where you can use the phone as a laptop.
My Oneplus 7T seems to have it but never found a use for it (its just basic screen mirroring). I think Samsung is the only one with a docking UI system (DEX) though
Huawei also has it. I used to have a P30 Pro, upgraded to a Pixel 7 Pro just now, and I was actually surprised to find it doesn't support this.
It's quite useful sometimes when I'm in a satellite office and I didn't bring a laptop, I can just plug my phone into one of the guest workplace docks and it's quite productive. Eagerly waiting for Android 14 to bring this to the Pixel.
