Homeplugs (ethernet over power) are fine for some things, but they add so much latency to the network.
Wired is so much better.

You can send stuff through the home power sockets? WTF first time I heard this sounds like magic
It's old magic too and in a pinch it works reasonably well.
We use this as a networking option for an old dorm I was in which didn't have ethernet and the concrete walls between rooms made Wi-Fi unusable.
Blocks of rooms were not separated on different circuits which made this possible
Was it not possible to draw Ethernet, or did they just want the cheapest solution? I consulted for a place that had a similar situation, and it was unacceptable for most of the students due to the jitter. So we drew Ethernet and put mini APs in each room.
It's always possible, but not often practical, especially when you don't have permission to drill holes in those concrete walls.
I suppose you could do surface runs, but those are ugly and more vulnerable to physical damage.
But I wasn't facility. I was a student.
The dorm itself did not have internet and had no plans of running ethernet or providing internet to students.
I got internet through a wireless access point, positioned very carefully in window for a WISP. And they distributed that to rooms near me.
