You're definitely limiting your upside with an N100, but it might be enough like I said. It'll work, it's just a matter of how fast it'll be with everything you put on it.
I'd highly recommend joining the serverbuilds dot net discord. They also have a forum with pre-specced NAS build configurations, complete with pricing. People there are very helpful and will give realistic advice.
I think Jellyfin beats Plex on 4k transcoding (tonemapping?) with the iGPU, but fwiw I do not transcode 4k and add subtitles to them just fine. I use an nvidia shield, which direct plays 4k content with the added subtitles. Hearing about transcoding 4k content just to add subtitles is news to me.
