Public is okay.
FYI…
Make a Wi-Fi network public or private in Windows
When you first connect to a Wi-Fi network in Windows 11, it’s set as public by default. This is the recommended setting. However, you can set it as public or private depending on the network and what you want to do:
Public network (Recommended). Use this for networks you connect to at home, work, or in a public place. You should use this in most cases. Your PC will be hidden from other devices on the network. Therefore, you can’t use your PC for file and printer sharing.
Private network. Your PC is discoverable to other devices on the network, and you can use your PC for file and printer sharing. You should know and trust the people and devices on the network.
