I ran one hdmi from the floor level to my wall mounted TV......and a big ass conduit. Ain't nothing I can't add. I am always hesitant to add "2 coax, 2 ethernet, 2 HDMI" blah blah blah for 'future use' because the odds are by the time I need 2 of all that crap, there will be some new end all be all requirement.
I currently have one coax to every room in my house and one Ethernet cable. So far I have used only coax....because Dish uses MoCA networks.. You don't even need the Ethernet now. LOL.
Probably won't be much longer before we have some kind of fancy wire that handles everything....USB-C is over here waving at me on my desk. :/
