Thanks for the thoughtful response and links! I actually think you've convinced me to go back and try to complete the whole French KOFI deck, as there are certainly gaps in my verb conjugations.

For hearing French, I went through the old FSI French phonology course at the beginning, as well as all the grouped (A1/A2/etc) comprehensible input from this channel: https://www.youtube.com/@FrenchComprehensibleInput/playlists. Oh, and I did a bunch of the French listening comprehension on Yabla for a few months: https://french.yabla.com/.
