Thank you very much! What does -ac do?

It mixes the audio channels of the input down to stereo
Manipulating audio channels

I only want the left channel so will be using ffmpeg -i <infile> -af "pan=mono|c0=c0" -f wav <outfile>

I’ve needed to extract audio from MP4 videos a few times. An mp4 to wav converter is a convenient option when you want to work with the audio separately.
