Obviously, I’m not looking for pristine sound; but it’s right at the point where I could consider using it and if there’s anything that can be done to get it even a little better, I’d really appreciate it. This is a really important interview for me.

The digital-artefacts can be made less conspicuous by shaving-off some of the the high end, (>3500Hz), using an equalizer.
Then IMO intelligibility can be improved by dynamic-range-compression e.g. LevelSpeech2.
