sharing files to laptop via data cable
In android, when a data cable is connected, a notification comes to choose how to use the cable. By default it is just charging and there is an option to share files and this exposes the storage as a block device/usb storage to laptop. I think this should be enabled in Librem 5 as well. Jumpdrive has that functionality already, so it may be easy to integrate. Though mounting same disk in both places can be tricky.
