I had the same problem when (finally) deciding to reconfigure a server
to use NetworkManager instead of the old network service.
I manage to make it work with a "drop-in" configuration file for
NetworkManager-wait-online.service that replaces the call of nm-online
by waiting for all the wanted routes to be up and that a gateway is
reachable. See attachment.
For this server it's really long, and waiting for the routes is not
sufficient at all:
Dec 17 12:46:37 xxx bash[1047]: Network Manager Wait Online routes
took 9 seconds
Dec 17 12:47:07 xxx bash[1047]: Network Manager Wait Online gateway
took 30 seconds
Dec 17 12:47:07 xxx systemd[1]: Started Network Manager Wait Online.
