Ideally you don't want to transcode, a powerful computer can do it but there will be quality loss.
It's weird the utilization is at near 100% with transcoding disabled, are you sure its not transcoding? If Jellyfin, VLC and mpv all fail to play it correctly it has to be the hardware on your streaming box.
A full desktop PC with adequate cooling can run at 100% for a long time but I doubt your Synology is designed to run full out for long periods of time. But still you don't really want to do that if you don't have too.
I would suggest you get a Roku Ultra ($99) or NVIDIA Shield ($150-200). It will be able to direct play h265 and most other codecs, the Roku Ultra supports AV1 which is starting to be used more by YouTube and is the newest codec in wide use..
The external players are playing badly because you don't have a hardware decoder for h265. A modern computer or most of the newer streaming boxes have a hardware decoder for most codecs which takes the work off the CPU.
If your client device was a full pc you could upgrade the graphics cards to one with these decoders and it would offload the work to it but of course you can't do that with a streaming box.
