It doesn't matter. As Robert says, the node's hint is used only in optimizing.

I think my final question about then is, what about MatrixTransforms? If I have
a Matrix Transform with an updateCallback that sets it's matrix every frame,
would it matter if it was static or dynamic?

This is actually something I have been curious about for exactly how it is done
as well. What about if you have a Geode who you are going to add or remove
drawables to. Do you make those drawables DYNAMIC?
It's only the contents of StateSet and Drawables that your need to mark as
DYNAMIC if their contents are changing. If only their ownership is changing
they you'd don't need to set them to DYNAMIC, even if you remove the StateSet
or Drawable from the scene graph it's still safe as the rendering back end
takes a reference to StateSet and Drawables that it's about to render.
