If this is new construction I would use the Carlon adjustable boxes. They are available in single and 2-gang and adjust from 0-2". We use them anyplace we are not sure what the final finish material thickness will be such as in tile, cabinet backs, baseboards, paneling, etc. We adjust the box depth to approximately what we think it should be then when we set the device make the final adjustments. They cost more than regular single gang boxes but about the same as if you were to include the goof ring needed with the regular single gang box.
