Note that VLC isn't your only choice. I use mpv a lot myself.

youtube-dl looks for a config in ~/.config/youtube-dl/config.
Mine says:

    --cache-dir '~/.cache/youtube-dl'
    --add-metadata
    --xattrs
    --no-mtime
    -o 
'%(title)s--%(uploader)s@youtube--%(upload_date)s--%(resolution)s--id=%(id)s.%(ext)s'
    -f 'bestvideo[ext=mp4]+bestaudio/best[ext=mp4]/best'

The -f option is what you want for control. It doesn't always seem to do 
what I want, but that is the section of the manual you want.

The above often chooses a MKV download for me, maybe because of audio 
formats? For purposes of my DVR I convert MKVs to MP4s with:

    ffmpeg -i blah.mkv blah.mp4

I don't know if the "original" format is a knowable thing, I just 
presume youtube itself doesn't upscale and that therefore the highest 
res should be the original.
