It really depends on accessibility to running cables. Don’t cheap out, run CAT6 at the minimum. If you think you might need an extra run to your media center, RUN IT. I prefer my AP’s ceiling mounted and even if you don’t have the money for the AP’s themselves, run the wire now. Think you only need a 8 port switch, get the 16. Make sure you have plenty of receptacles for all of your devices and plan to have a UPS powering those critical devices. Networking devices create heat, make sure they can breath. POE is your friend, have a switch that is POE. Learn about VLANs and make sure your router supports them in order to separate your secure networking devices from your IOT and guest wireless network.
