Depends on what you’re doing with it. For many things it will run fine off of a 3A 5V supply, which almost any usb-c adapter will do. But as soon as you start hanging any USB devices off of it, IIRC you need a 5A/5V supply which is unusual outside of the RPi-specific one.

Yes, and it depends on the devices. 5V/3A will limit USB power to 600mA. Could also use a powered USB hub.
