I had a similar experience moving into a new apartment that had ethernet sockets in all the walls. Took me a while to realize that the cables connecting the sockets up were oldschool Cat5 (100Mbps max) cable, so even though I was plugging Cat6a into the wall it didn’t do a lick of good. Wi-Fi 6 on the other hand is giving me a little under 1Gbps.
I wired up my office, and when I speed tested it, the shitty Ethernet adapter in my USB-C dock was slightly slower than just using wifi.

You can pretty reliably pull 1G with cat 5 over household distances (10m or so). More likely it’s the equipment limiting the speed.
Could be all the way down to 2 wire cables if they cheaped out hard enough
Nah you need a minimum of two pairs for an Ethernet connection.
Ethernet over coax was very popular until CAT cables replaced them.

There’s hardware that does it with one
Interesting edge case. Not really relevant though.
It is part of the ethernet standards now, though
