Say, something like this was found on the moon. How might it be
aligned? What diurnal/seasonal events might it be able to predict?
Could it be used as a working calendar? Are there significant
extrasolar events that could be better observed from the moon than
Earth?
TIA for all answers.

It's unclear to what extent Stonehenge can be said to have performed all
the functions you mention ... Anyway, the Earth is always in more or
less the same place in the sky as viewed from any given location on the
near side of the Moon, so only the Sun's rising and setting positions
could be marked. They would vary over a smaller range than at a
comparable latitude on Earth. Tracking eclipse cycles could presumably
work in the same manner as has been proposed as the purpose of the very
early "Aubrey holes".
I don't know what you mean by "extrasolar events", but the lack of an
atmosphere would make the most significant difference in observing
conditions.
