WiFi is much more convenient if you live in an apartment, or if you're renting and can't tear down the walls to run ethernet.
You can use "fish tape" to run wires in walls, mostly non-destructively. Many fish tapes glow in the dark so you can drill 2 small holes, do what you need to do, spackle, and paint.
You probably still wouldn't do any of this in an apartment of course, but I figured I'd throw out the pro tip.

The hard part is getting off your butt and doing it. Like every other side project.
Cutting in the box and making up either end of the cable generally takes longer than running the drop.
