Quick check questions (decision tree)
Is there clear motion or a path (walk/run/fly/roll/climb)?
Yes -> consider off; if it's static position only, use a spatial preposition.
What is the path relation: through, across, along, toward, into, onto?
If it is not this page's relation, switch to a closer option like on or out of.
Is the sentence about reaching an endpoint (enter/land/arrive)?
Yes -> an endpoint preposition (into/onto/to) may fit better; No -> choose by the path itself.
