Oh, Match is great. For a typical, simple PC or laptop, you no longer
have to worry about whether your wifi is called wlan0 (kernel, and
iwd), wlo0, wlp365s7 (onboard/slot/path), or wlxf1dd1efadd1e (USB),
it'll get matched nonetheless. Ditto for e* and ethernet.

I don't understand this. If you're actually running two subnets with
255.255.255.0 netmasks, and they intercommunicate with each other
(your computers on subnet 1, and Verizon ISP on subnet 0), then you
must have a gateway on each subnet for them to communicate through.

But backing up… the systemd-networkd configuration above is that of
Christoph, who wrote that their system had been (a) switched to
systemd-networkd from systemd-networking, and (b) purged of avahi
packages to eliminate 169.254.x.y addresses. So I'm not sure what
there is to fix here.

But (a) raises the question of what systemd was running /before/,
which was presumably what was giving rise to 169.254.x.y addresses.

And, while I can add an innocuous 169.254.0.0 route to a system
merely by installing ifupdown and avahi-autoipd, that route looks
like the second line here:

  default via 192.168.1.1 dev enp2s2 onlink
  169.254.0.0/16 dev enp2s2 scope link metric 1000
  192.168.1.0/24 dev enp2s2 proto kernel scope link src 192.168.1.10

and not like the OP's (ie Geert's):

  169.254.0.0/16 dev ovs-system scope link src 169.254.201.7 metric 1004

(which has been grepped out of its context).

Cheers,
David.
