It doesn't matter what breed it is, the horse just needs to be broke and suitable for the rider's needs.
Essentially, yes. A well broke horse of any breed will be able to do what a typical advanced beginner wants to do. It knows where its feet are, it follows directions, and is fairly tolerant of mistakes b/c it doesn't rely on its rider to hold everything together.

Breed is irrelevant, but thinking about breeds is fun!
