Yes, except that most devices use Ethernet. So, at the end of the day, you still need Ethernet cables unless you want to deal with an additional switch or converter in every room.

I disagree with that for two reasons. First, my central switch is probably capable of both copper and fiber. Second, how many wired devices do you have spread around your house? Let's say I have an above average number of devices: a router, a NAS, two access points, and three desktops. Router, NAS, and one access point can all be adjacent to the switch and avoid any conversion hassle. The desktops are using fiber so no conversion hassle there. That leaves one copper cable or converter needed for the other access point.

Fiber/10Gbase-*R is Ethernet too. Please say copper/RJ45/base-T when you mean copper/RJ45/base-T.

Indeed, that's largely why I decided 10gbit at home isn't really worth it. The current 10gbit ethernet stuff is expensive and power hungry, the enterprise stuff is hard to use on consumer gear. And the only real use case is super fast access to a nas.
