Best golem for onboard a flying ship

[Tiny Coffee Golem]

I'm a caster who can make golems. What's the best one to create for a ship?

That depends. An iron golem can double as an anchor when necessary.

More seriously, the tonnage of some of the heavier golems can be a serious impediment to the ship's balance if the GM makes a point of it. Lightweight is the key. You may want to consider a flesh golem, since they're good in stormy weather (being hit by lightning or St. Elmo's fire is generally not considered a good thing by anybody else.) Designing one with a fly speed could make it more useful yet.
