Ah, therein lies my failing - I assumed OS supplied units wouldn't
need adapting...

Adding After=network-pre.target to dhcpcd.service seems to have
resolved it, and taught me a lesson in the process.

Is there an obvious reason I'm missing why these aren't distro
defaults? (Is this a "bug" in the network management tools' unit
files? Would "fixing" this at the distro level have any likely side
effects?)
