Before we start:

"virtual ethernet devices" are something totally different than you are
doing here. You just want to put multiple IP addresses on one interface.

"virtual ethernet devices" are for example used with virtualization or
docker, to connect an isolated VM or container through the host to the
network.

One of "allow-hotplug" or "auto", not both. And you have a typo there,
it should read "auto eth0".

No need to duplicate the nameservers. Also this line only gets used if
you use the package "resolvconf". On servers with static IP
configuration I usually get rid of this mechanism and set the
nameservers myself in /etc/resolv.conf

Yes, everything is fine. 

Side note: I'd truly randomize the IPv6 addresses, so the subnet is not
as easily scannable from the outside.

I don't understand the question. Do you mean "systemd-networkd"?
