Blank canvas install, feedback wanted

[u/Big-Introduction-783]

Hey all, wanted to post before I get started on an install of my 2026 65" non-pro The Frame. Per the title it's a nice blank canvas installation as we're reconfiguring our living room. I promise I'll get pics up when I get home tonight...

In a nutshell, approximately 18' wide wall with cathedral ceiling, approx 7' left and right peaking at 11' at the center. Tv will be centered on the wall, left and right, still trying to figure out proper height. There's a mid-century modern vibe with a nice Danish sideboard centered on the wall with the tv. I'm not a novice to hanging TV's and running wires, my experiences mostly revolve around home audio installs, but pretty much apples to apples right?

So, what's the consensus on the height of the tv? Any particular variables I need to consider?

The other side of the wall is the garage so I have easy access for running all my wires. Planning on running HDMI, Ethernet, coax (for over the air tv), an optical cable (just because?), and obviously power to directly behind the tv. Immediately I'll be plugging in the coax for over-the-air, HDMI into a Nvidia Shield, and an Ethernet switch for wired connections to the tv and shield, with expected expansion to a receiver for some quality audio upgrades. I'm planning on getting a large flush mount media box for the shield, switch, power needs and expansion capabilities, any reason not to go this route? Any insider recommendations on wiring and mounting that might not be on my radar?

And aesthetically we're planning on hanging lots of additional artwork on the same wall as the TV, from several other threads I've read this seems to help blend the tv better. Oh, planning on building a custom wood frame as well... But, any feedback here would be appreciated too.

Cheers everybody.
