Indeed, the system doesn’t know the airports ILS status and always treats it as the highest available aircraft capability, so usually CAT 3 DUAl/SINGLE.

For the NPA it depends how it is coded. If the approach is in the database with a runway point, it will usually revert to basic modes during flare (triple click), which mens that one gets flight director guidance well below the 250 ft, haven’t tried the autopilot, but i expect it to be a regulatory limit rather than an aircraft enforced one. In the end it does also depend on equipment status, with FLS it is 200ft, LPV it is 160 ft and GLS it is either 160 ft or 0 ft if AUTOLAND is displayed.
