I'm just leaving everything as flac right now but wanted to share my invocation for rclone, it's been a bit faster/cleaner for me than rsync (probably I just don't know rsync well enough but when you have a hammer everything is a nail)! Obviously very specific to my particular music library but an example of an rclone invocation at least.

Code:

#!/usr/bin/env bash

set -euo pipefail

rclone \
  sync \
  --ignore-case \
  --exclude \*.jpg \
  --exclude \*.webp \
  --exclude \*.mkv \
  --exclude \*.mp4 \
  --exclude \*.aac \
  --exclude \*.m4a \
  --no-update-modtime \
  --progress \
  /share/plex-media/music/ \
  /share/external/DEV3303_1/Music/

The script I shared actually only copies over files with audio to the target directory (and adds the album art, if selected). Everything else gets ignored by it. I haven't tested this, but i'm pretty sure it would grab  just the audio from a movie file if the movie had audio which needed to be converted, and would paste the whole movie file to the target directory if the movie audio didn't 'need' conversion.
