Screen-and-battery assembly work is documented alongside a battery-only guide; the USB-C port is part of a daughterboard.
What to check before buying
Screen options
iFixit has both screen work and a screen-and-battery assembly guide. The assembly can include the frame and cell, so two display quotes may describe different parts.
Charging
The USB-C connector is soldered to a daughterboard; replacing the port means replacing that small board, not desoldering only the socket in the documented procedure.
