I would say that "specific poetic forms" like sonnets and elegies and odes are not archetypal.
Characters are the most common form of archetype: we see the same characters in the small town literature of Our Town that we do in To Kill a Mockingbird: the town drunk, the loner, affable policeman, the innocent child, etc...
Setting is also archetypal: islands are places of chaos in both Othello and Lord of the Flies, for example.
Plots are also archetypal: quest literature like King Arthur is not much different from Harry Potter or Lord of the Rings. They are all versions of a monomyth.
Specific poetic forms are just that, specific, and intensely subjective and difficult to re-create by other poets across time.
