PoE is a godsend that should really be in more consumer devices and households, alongside structured wiring. An AppleTV, Chromecast, or NVIDIA Shield can easily fit within the envelope of PoE+, as can many enterprise-grade switches and WAPs (see UniFi as an example). Converting AC to DC once at the switch is more efficient (in resources and often, but not always, power) than including bulky PSUs for every device, while simplifying the ease of setup for end users (in theory).

Whenever possible, I opt for PoE. It’s a damn shame it’s limited to a niche userbase given its myriad advantages.

My Chromecast uses USB C for its network. I got a power brick (official Chromecast) that also takes an ethernet cable and then provides a wired ethernet connection.

That being said, a quick Google search for "poe usbc" yields some devices that are much more expensive than the power brick I bought, but in theory would let you run a Chromecast from a poe ethernet port with wired ethernet.

I bought last year a device like that I think - was from some company named TexasPoE I think, and it took Ethernet cable, and output has usb-c with 1GbE and power. I sometimes use it with my iphone or iPad and do get the wired Ethernet connection and charging
