When I did two OC brother/sister sets for The Tyranny of the Fairires Destroyed, I used both types of brother/sister pairings. Philonice and Anaxandre's children are an older sister/younger brother pair, while Melicerte and Yphidamente's children are an older brother/younger sister pair.

Usually, in fairy tales with mixed-gender siblings, all except the youngest will be the same gender (like in The Six Swans, where the seventh and youngest child is a girl and the rest are boys). In most fairy tales with brother/sister pairs, it's unclear who is older. Hansel and Gretel is one of the few that makes it blatant (Hansel is older).
