Thank you for sharing so much material and so many details about you, Cecilia.
It is clear that the authors do not attach much importance to the 18 or more categories of adjectives. I think what you should make clear to your students is that the order is approximate. The second bullet point in the teacher's book is particularly enlightening.
I think your list omits nouns in attributive position (with only some of them denoting material) and participles, both present and past, which when designating the type of noun will tend to remain next to it, as in dancing shoes or baked potatoes.
Perhaps more interesting than the order of adjectives is the order of determiners for teaching purposes, don't you think?
