If your media server supports Docker containers, and has a way to schedule scripts then the following script run daily (or as often as you like) will sync a YouTube channel:

#!/bin/bash

docker run --rm \
  -v "/path/to/media/TV Shows/{channel}/:/downloads/:rw" \
  -v "/path/to/application-data-directory/youtube-dl/cache/:/cache/:rw" \
  -v "/path/to/application-data-directory/youtube-dl/tmp/:/tmp/:rw" \
  --cpus 2 \
  jauderho/yt-dlp:latest \
    --playlist-items 1:5 \    # only download the most recent 5 videos (remove this for the first sync)
    --add-metadata \
    --convert-thumbnails png \
    --download-archive /cache/archive.txt \
    --embed-chapters \
    --embed-subs \
    --embed-thumbnail \
    --merge-output-format mp4 \
    --remux-video mp4 \
    --no-overwrites \
    --output "%(channel)s - %(timestamp>%Y)s-%(timestamp>%m)s-%(timestamp>%d)s - %(title)s.%(ext)s" \
    --paths "/downloads/" \
    --paths "temp:/tmp/" \
    --write-description \
    --write-info-json \
    --write-annotations \
    "https://www.youtube.com/@{channel}/videos"
