For the .mount units, you could make them run after the network-waits-online service, thus making sure that they only mount after a stable network is up. Adding _netdev to the fstab mount options also does that, I think. 

The best solution I’ve found for this issue is to use .automount units for every network .mount unit. It will only mount the volume when it’s actually read or written to, which might be well after the boot, and uncounted it after inactivity. It prevents stale mounts if the file server reboots or dies too.
