@Tone I use the Pi camera (v1 since that’s what i had from an old project). It’s nice and compact. I can’t help you on the Cura settings since I do my slicing on Cura on the desktop. BTW, my Pi is connected to the network via ethernet port for an easier setup.
Below are some screenshots of my setup from an overnight print I did.
Pi camera and holder. It can swivel from the front of the bed to the right side.
I can send the gcode straight to OctoPi from inside Cura.
You can see your progress from within Cura if you like, or remotely from the web portal.
