Using that network adapter on the CX is hit and miss I've found. It will work fine when first plugged in then will cease to work after a couple of hours. It doesnt ever seem to become functional again unless you turn the TV off and on again. I've stuck to Plex on my Shield as lack of DTS on the set means using the TV means the sever has to transcode which works fine but would rather it didn't. The TV also struggles with a couple of DoVi files too.
Thus far I've not encountered any issues using the 920+ as a server and the Shield as client. The only minor hiccups are with individual bits of software. I.e. emby hiccups on a couple of files, Kodi does with a couple of different ones. Generally though Plex runs everything as it should, even files which burst up to 170mbs. I prefer Kodi in some ways after sorting it all out with Media Manger but at this stage Plex seem more stable. The only issues I'm having, which arent with the Synology or really the Shield, are issues with TrueHD files. The TV reads them as Atmos, which in my limited understanding they are (!?). If I play a particularly large 4k remux like Jaws the Atmos logo will appear repeatedly at the same points throughout the movie, as though it has lost and regained connection. The picture and sound remains unaffected but the logo appears which is irritating so I always use the alternate audio track. My money would be on the files haven't been pulled from the disc correctly as Atmos is read perfectly from Netflix, Disney+ etc.
