The only APV approaches I'm aware of are RNAV (GPS) to LNAV/VNAV minimums, LPV approaches, and RNAV (RNP) approaches. All other Non-xLS approaches are Non-Precision approaches with a horizontal ROC which requires an MDA. To use a DA in lieu of an MDA for these approaches requires OpSpec C073.
Further, MDA is generally no longer used when using CDFA method. Typically a Derived Decision Altitude is set 50' above MDA, for the decision point to land or go around.
