Salamun Alaikum,
Generally, I would incline to argue ‘yes’. When spoken to in the capacity as a 'Nabi' such as 'Yayuha-nabi" (O Prophet!) it generally implies an immediate context being addressed as a Prophet is not only a ‘messenger' but also one with hukma (authority) / command of his people. In the case of Prophet Muhammad, he was not only a spiritual guide to his people including his family, but also a community leader.
006.089
"These were the men to whom We gave the Book (Arabic: Kitaba), and authority (Arabic: Hukma), and Prophethood (Arabic: Nabuwa): if these (their descendants) reject them, Behold! We shall entrust their charge to a new people who reject them not"
Of course, Prophet Muhammad’s immediate 'authority' as a 'Nabi' would be first and foremost upon his people, but that does not mean that there is no wider guidance to be extracted for subsequent believers.
I hope that helps, God willing.
Joseph.
