Hello everyone,

I made the mistake of installing all my cabinets level and true in a
kitchen that is anything but.

That's not a mistake, it's the way to do it.

Actually that is the answer. You will need to infill with wood, but not too
carefully, best to have about a quarter inch gap between the wood infill and
the masonry. Then squeeze acrylic caulk into the gap, smooth off with a damp
cloth and paint with the wall colour. Use masking tape to keep the caulk off
the cabinets.

That is absolutely the best practice, least visible, no gaps, no joins, no
extra lines or trims or mitres: tidy, quick and easy.
