Have you considered a decent mesh wifi system? I have a reasonably sized house and it works for me, and I stream a lot of HD and 4K video content all around the house. I really can't see a situation where I'd need a wired network anymore, and as I've been ripping out old phone cables/sockets and TV coax around each room as I've decorated I think to myself if I had ever installed wired networking I'd likely be doing the same to that in 5-10 years.
