ii) scribe and cut the lower edge of the plinth to match the varying
height of the tiled floor

Bear in mind the plinth does not have to be flush to the underside of the
units, it will be hidden by the overhang. Also that the plinth is probably
chipboard or MDF, that won't take kindly to repeated wetting from the
floor, from splashes or cleaning. Keep the bottom of the plinth a couple
of mm above the floor.

The prefectionist would scribe to each tile and grout line individually. I
think I'd just do a few spot heights along the lenght of the plinth and
cut to those, ensuring the 2mm gap.
