Measure tags are just that, tags that get put in the OSM so that measures can make use of the data. As you have learned they do not on their own alter what gets written to an IDF file or what the EnergyPlus simulation results are. The first use of these was related to tagging space types for early ASHRAE AEDG measure to know the intended use type of a space without having to infer it from the name. This is still used today, including by the baseline automation and create typical measures. Later measure tags were added or constructions in support of specific workflows for CBECC-COM. It would use those tags to generate OSM constructions which in turn are translated to IDF constructions. I'm not aware of other measures outside of CBECC-COM that make use of the measure tags for construction, although some measures might make use of intended surface type.
