I'd call the lord of the rings EE directors cuts because they're quite literally PJ's cuts. Those are the movies the ways he wanted them, pacing and all, before trimming them down for theatrical release.
Majority of the fellowship scenes were actually the last scenes of the trilogy to be filmed, but I don't think they'd ever plan on having both the return of the king saruman/grima scene AND the scouring of the shire. iirc it was briefly considered but they felt it was important that the shire retains the motif of being a home and safe haven
