It’s questionable if they’ll ever consider landing a Starship on the moon. It would require multiple orbital tankers to give it enough fuel (unless it was a one way trip). And there is no possibility of ever manufacturing metholox on the moon.
That schedule change wasn't related to a schedule slip on starship, it was a decision to switch from a small mission (by number of people) using a falcon heavy and crew dragon to a bigger mission using starship.
It might have been related to the schedule slippage on crew dragon though, considering they are just now ready to fly astronauts on crew dragon.
