Do I need Thunderbolt 4, or will USB-C work?

If your laptop has Thunderbolt ports, always buy a Thunderbolt 4 dock — you get guaranteed performance and dual 4K support. If your laptop only has USB-C, a USB-C dock with DisplayLink technology enables dual 4K monitors at the cost of requiring a driver installation. For a single monitor setup, basic USB-C docks work fine without Thunderbolt.

Can one dock replace multiple separate adapters?

Yes — that's the whole point. A good docking station replaces: USB-C to HDMI adapter, USB-C to USB-A hub, Ethernet adapter, SD card reader, 3.5mm audio adapter, and power brick. One cable in, everything connected.
