> which is why I export in mp3 as well as wav; wav for higher quality, and mp3 for labeling purposes; I could probably just use flac but compressed audio like mp3 also has the benefit of being less space intensive

You could replace the WAVs with FLACs and save a bunch of space on that account. Maybe enough that you realise you don't need to keep both lossless (WAV/FLAC) and lossy (MP3) copies around. Since FLAC is lossless, it will have the exact same audio quality as the WAV files they'll be sourced from. (And, as you mention, FLAC supports tags directly.)
