not sure which cpu that Synology has, but I run jellyfin on ugreen nasync dxp8800 plus which has intel with QSV and it breaks no sweat in both transcoding (if needed) and serving over 10GBE.
It's a Synology DS720+ with a Celeron J4125, 2GHz, 4 cores, 2GB of RAM.
I thought it would be fine, because Plex has no issues, but it was painful. Every client I tried on the AppleTV was equally painful, and I didn't even try using a client until making sure all the metadata was downloaded and setup via the web UI. I was very deliberate and did one thing at a time, spending a whole day on it (mostly waiting and browsing to different screens to force metadata to get downloaded and cached).
