Is there a payment vendor that can handle CIP, provide a secure data vault, process payments, move funds, and manage compliance reporting for third-party marketplace platforms?

Any full-stack payment service provider will do that for you. That is what full-stack is all about. Ben Brown has given some good examples.

Just as a FYI, they will not extend the licensing ou toyou (if that is the case) and nor will you be absolved of your regulatory obligations (if any).
