Even with wifi, big houses or tough RF environments need mesh units to get ubiquitous wifi coverage. And there, ethernet wired backhaul is far, far superior to wireless. So maybe your dad was prescient in a different way.

The issue with wiring your house for Ethernet is that 2003-era Cat5 that a random builder or DIYer grabs from Home Depot isn't going to carry nearly as much as the Cat6A cable you would want if you need the cable plant to have a chance of keeping up with network capacity growth. But that needs quality installation.

I had a fairly extensive Ethernet and audio speaker setup in the course of a couple of house renovations. Much of that is trashed from smoke mitigation after a kitchen fire. Will pretty much just use WiFi from here on out.
