Using a mac on your network:

1. I looked into Sidecar ( https://support.apple.com/en-us/HT210380 ) to use an iPad as a second display with a mac, but it says that only iPads 3rd generation (2019) or newer are supported. Models: https://support.apple.com/kb/HT201471#ipadair

2. The mac's built-in screen sharing is a VNC server.

3. When you search in the ios app store for "vnc" the list of other suggested apps seems to have a bunch.

Thank you for the research. I didn't know that the mac's screen sharing was VNC, but that makes sense.
