Communism isn't about picking a model and copying it, that idea was abandoned in the 1800s. Engels wrote an entire essay on it, Socialism: Utopian and Scientific. We can look to AES states and see where they found success and failure, but no AES state thus far has come from anything comparable to the 2024 US Empire's unique material conditions and productive structures, so obviously we can't copy any one country one to one, nor would we want to.
