The number of voicings is practically unlimited, so I guess you’re always learning new ones (slowly as you play more tunes). The 3 and 7 are the important ones and the other notes fill things up, so that gives you too much freedom perhaps. Limiting yourself helps, practice 137 chords, type A and B variations. That would be the basis; in Hayden’s videos you can see him spreading out most chords quite a bit. So for example 1 and 7 in the left hand, 3 in the right plus the melody note (depending on the chord).
Tunes will implicitly teach you some voicings, as you start thinking of combinations of chord and melody note. These have patterns in themselves (which I read little about really), like a So What being usable when you see a minor chord with a 5th in the melody (inversions give more options here).
For myself, I try to practice the basics (not go overboard with all the options) and spread my wings a little when following the arrangements. I actually started an Excel sheet where I mix chords and notes, e.g. Min7+5th=So What, or variations with upper structures. But there a lot and inversions make it possible to have more melody variants. For example a triad as upper structure has three inversions which each offer a possibility for the melody note.
