I pre-wired my house in the boonies with miles of cabling. Two RG6 and two Cat5 to each drop, 64 drops total in a 4000sf house. Phones in the bathroom? Check. Never used those drops. Printer in a closet? Check. I used one of ten. The only uses I found for Coax was to the front door camera, satellite dish for TV, and satellite dish for internet - and the internet dish didn't work out because the receiver needed to be much closer to the dish to maximize signal quality and it used Cat5 from there. I worked from home and had a bunch of computers in my office but nowhere else. Had some floor drops in the living room we used for laptops, and a couple in the basement for the automation system. So most of my pre-wire work was wasted. Used ALC for lighting with a twisted pair to each wall switch.
We're building another house now. UPB lighting so no hard wires there. I won't run anywhere near as many drops, maybe 12 in the entire 4000sf house and 2000sf shop and almost no RG6 - a little for a satellite dish prewire but I doubt if we'll ever install one. We're now using a mesh WiFi router (Linksys Velop) with outstanding results and will rely on WiFi for most functions. If a device needs hard wired ethernet, and is located away from a drop, a WiFi access point will work fine, no need to drag a cable to a switch across the room. Printers are all WiFi. TVs are WiFi (but I will put a hard drop by those anyway). With Sonos audio I don't even need much in the way of A/V and speaker wires anymore. Mesh router nodes are WiFi, they just need AC power. Most of my pre-wire effort will be for security and PoE surveillance cams rather than for computers and entertainment. Heck, with Sonos speakers I don't even need speaker wires anymore.
