Hi Bjørn, your comment makes me digging deeper in why this modem can not working in both modes.
I installed native Windows on the target device and tried to make this modem running in native Windows. There I saw that after using the modem the first time Windows issued a firmware update of that modem. After that firmware version 18500.5001.00.03.25.24 was installed. Now switching back to Xubuntu 20.04 I tried the usb approach once again. Now the usb switch worked in general. The modem was available at the USB bus but it was not possible to get a connection because of the issues described in https://github.com/xmm7360/xmm7360-usb-modeswitch and https://github.com/xmm7360/xmm7360-usb-modeswitch/issues/23 After that I booted native Windows once again and installed an older firmware version. I did this by forcing installing an older driver and modified the FWUpdater config file a bit. https://download.lenovo.com/pccbbs/mobiles/nz3wj22w.exe After that I had firmware version 18500.5001.00.01.20.86 running. Using this firmware version it was it was possible to get a connection in Xubuntu 20.04 using the usb switch. So, it looks like that directly after this devices leaves the factory there is just a bootloader firmware installed and no "productive" firmware. Using the PCIe mode it was still not possible to get it running with https://github.com/xmm7360/xmm7360-pci. The kernel driver can attach to the device successfully now but the python script failed.
