Does "nmcli nm enable true" help?

As you see, it is NetworkManager manager which disables the network
interfaces whenever there is a suspend request, not systemd.

I assume you are not using systemd as PID 1 as the log message
"org.freedesktop.systemd1' failed" indicates?
This means you won't get a proper resume signal. NM listens to that
resume signal and re-enables the network interfaces. Since it doesn't
get that signal, it simply stays in disabled state.
