All of that is true although I would add there's a lot more variation than only Butterbreze. Therese Käsebreze, maybe with additional ham or salami, there's Pfefferbreze, Mexikobreze and so on.
But to come back to the original point. No one eats them with Sauerkraut.
Yes, the first part of my answer was rather limited to Bavaria, where Brezn can be part of a meal but not along with Kraut and where Butterbreze is the most popular variation if not part of a meal. Also some fresh cheese with herbs instead of butter is common. Afaik the other variations are more popular outside of Bavaria.
