Did Kathryn have a choice of being the Captain of a tiny ship, or a Commander on a regular sized ship, and she chose to be the Captain of a tiny ship?
Memory Beta cites Janeway was captain of the USS Bonstell(Oberth class) for a few years before she got Voyager.
Then again Memory Beta also says that vessel was destroyed at Wolf 359, so that's fan wikis for you.
Either way, it would seem to indicate a pattern of getting the captain rank and working your way up to bigger ships as you go. Janeway does strike me as the type to say yes to being CO of a small ship than XO of a big one.
