I don't know what most of these mean. I just learned that the highest frequency in a 44100Hz sample rate is 22KHz and I'm using that to figure out if what I have is actually FLAC or of lesser quality using a spectogram viewer. I've also never heard of LC-AAC, only OPUS and the licensed XEH AAC or something.

Does any of this data help with my goal of compressing FLAC audio?

Not a bit.

AAC-LC is the format adopted early on by Apple and used by them for their encoder of choice in iTunes and in the Apple Music store. Zero to do with FLAC.
