That's completely fair, it's definitely just opinion as to what to include. Getting to lunar orbit can reasonably be considered a separate challenge to landing,

That's completely fair, it's definitely just opinion as to what to include. Getting to lunar orbit can reasonably be considered a separate challenge to landing, so it might make sense to separate them. In that case though, I think Apollo 10 should at least be mentioned in some capacity, as it was a dress rehearsal that came within 16km of the lunar surface, and tested much of the lander's systems. Not listed as a failure or success, just mentioned, as it's a very relevant test.
