I have coaxial cables everywhere, but my HDD receiver in the living room also streams over the network to and from all kinds of devices (e.g., reads/writes to NAS or FTP, streams live/recordings to the tablet, etc.). In principle, network/WLAN in all rooms would have been sufficient. However, you then become quite dependent on one device (that’s why I initially laid coaxial cables everywhere; you never know how you might want to do it later). Otherwise, I am not a fan of wireless. Despite advanced technology, the range/transmission decreases significantly with solid construction when you are a bit farther away. It usually suffices for surfing, but if you want a lot (e.g., also retrieve data from a NAS or make a backup via LAN), WLAN is noticeably slower and more prone to errors than a wired network.
