Hardware advice

For the OS, I'd opt for Ubuntu 24.04 over Debian 12 if you choose an Intel Arc GPU due to better out-of-the-box support for Intel Arc. You can get Debian 12 to work with Intel Arc with backport kernels and whatnot, but Ubuntu 24.04 just works from the get go.

If you use the GTX 1060, it doesn't matter. Having said that, if you have the budget for it, definitely get the Arc A380 for AV1 encoding support.

I'm assuming you mean RAIDZ1 and not RAIDZ5. As in 1 parity drive.

While the TV itself is fine, IMO you should get an external smart device based on Android TV or Roku. I, personally, don't care for WebOS.
