I would do 2 more singles, and pick another one for a video.
2nd single would be Another Day. 3rd single would be either Hollywood or Mask. IMO I think Mask would do better because HT has that dumb spoken segment.
For the last video for the album, to close out the project so Sony/Estate can start working on the next project....a video to "Much Too Soon" should be done.
If there's footage of MJ recording this song, it should be revealed. If not, maybe a video with never released video footage would be neat. Maybe this is something The Estate/Sony & Katherine can work on together since everyone in all 3 parties seem to love this song the most.
