local mounts are by default ordered before remote mounts, so you have
dependency loop. Systemd resolves it by deleting one of units in this
loop. Depending on what unit gets deleted you get different results. I
do not know how deterministic algorithm is.

Yes, systemdm will create mount point if it does not exist. I am still
unsure whether this is a good thing.

systemd already adds dependency on network-online.target to network
mounts. But do not forget that you need something that actually
implements waiting for network, otherwise this requirement is

systemd adds equivalent to RequiresMountsFor=mount-point so
x-systemd.requires here is redundant.

Try adding _netdev to each mount that depends on /home to order them
