If you are not stabilised at VAPP at the FAF, then the approach is decelerated.
IMHO, as long as you are at an appropriate speed at the FAF (with F1 selected minimum - F2/F3 may be needed for steeper/tailwind approaches) there isn't an issue.
If the CDFA approach is flown in Final APP, then decelerated approach is fine. If the CDFA is flown using V/S or FPA for the vertical mode, then I would opt for early stabilisation.
