The easiest way would be to buy a PoE adapter that takes in PoE and splits to Ethernet + USB-C power plug. I use those with many boards (even Pis from time to time, if a HAT won't fit), and they work as long as you only need a few watts.
Oh those exist, true. I have a PoE switch where I am not using any of the PoE ports so I have a fantasy of having multiple RPi's or other single board computers being powered by PoE running various stuff for my home.
Also I had to spit take when I noticed the username. Absolutely love your YouTube channels, thank you for taking so much time creating high quality videos.
