Go back to the template idea...make one from either hardwood or a piece
of angle if you have it (since you said you have a drill press, this
should be easy). Go with a twist or Forstner bit (although if you make
a pilot hole first, a twist drill bit should be ok). To
minimize/eliminate the tearout, clamp a piece of hardwood or flat iron
on each side...

I have only access to the side /inside/ the medicine cabinet. The other
side is buried behind the plaster wall.

Whether there is a 14 mm router bit I don't know, I've not researched
metric sizes, but if it is actually a 14 mm hole required by the hinge,
there has to be a corresponding tool...

Well, I've a 14mm brad point bit coming from Lee Valley, but I expect it
will tear out like a twist drill.

You will be pleasantly surprised. A brad point bit has cutting spikes
at the edges, so it makes a clean cut in wood.

The drawback is they (bradpoints) are only good in wood, or wood like
materials. They don't cut metal.
