Here's the bash script I use locally, tailored to my habits and needs:
1. I always grab the "original" audio at best resolution
2. If descriptive audio is available, I'll grab that, too, at the lowest resolution, and tack " - Descriptive Audio" to the filename
3. I snag all the english subs.
This script scans the current working directory for MP4 files (ignoring descriptive audio), then matches a descriptive audio MP4 if found, then looks for forced subs, then subs, then CC subs, muxes the whole thing, then does some property edits. There are optional args to change the audio track naming (-a for normal audio, -d for descriptive).
EDIT: This doesn't handle subdirectories at all. Just a lot of errors...
EDIT: Updated to limit find to the current directory
It's pretty specific to how I like things named and ordered, but it isn't hard to customize it. Works as written in gitbash on Windows, but would probably work on linux or osx with a change to the mkvtoolnix base path.
Example - mux everything, using "Surround" as the default audio track name and "Descriptive" for any descriptive audio found:
