I would warn against those. This unusual case needs a thorough review, and an expedited passport request could result in them denying it instead of giving it the time and attention it deserves. Then once it's denied it could be an expensive legal battle to get it approved.Start an application for Green Card, try an expedited passport and N-600 for good measure.
Applying for a green card could create a problem in that it could be seen as an admission of not having citizenship. It could even result in the N-600 or passport application being denied. Applying for the GC should be used as a last resort; something to pursue only if the N-600 or passport attempts either fail or remain undecided in the month before he turns 21.
