Earlier quoted context omitted.
Getting stuck to 1 Gbps is somewhat crazy, as even the slowest laptop and PC M.2 SSDs can do 10-20 Gbps easy. Fastest ones 50 Gbps+. But I guess most people don't transfer files in their local networks anymore and use their network purely for internet access.
I rent an apartment in a building that was erected around 2015. They laid an ethernet connection... with a 100Mbps bandwidth limit. Some people just don't care.
I'm busy retrofitting Ethernet in my house by pulling cat6 through the walls and pulling out the old cat3 phone cabling. It's much harder work doing two cables (not least because none of the phone cables were in conduit, so it just starts off harder already) for each pair of ports, but it's very much worth the effort.
