It's more expensive, but I grabbed a vero 4k a couple years back and have been really happy with it. They've since put out a new model with av1 support. https://osmc.tv/vero/

It's just about the best possible dedicated jellyfin client box out there, so I felt it was worth the extra squeeze when I got it. (HDR support even!) It's all open source though, so support for things like YouTube, netflix, or any other streaming doesn't really exist in user friendly manner.
