What are using for 4k x265 content?

So far the nVidia Shield seems to tick all the boxes but they're pricey.

Plus it means my ChromeBox will be retired to a bedroom which seems a bit soon but to be honest it's getting to be more of a problem since I bought a 4k TV.

For HEVC/H265 4K SDR content - AMLogic S905-based boxes are a good fit.  For HDR then S905X (and now S912 I believe) boxes are popular, though the Shield is a better fit if you want Netflix and Amazon UHD HDR too.

S905/S905X/S912 boxes will be best running LibreElec - or OSMC in the case of the well regarded Vero 4K.
