I found FAA Advisory Circular AC 120-108 to be a great resource. The AC provides guidance on using continuous decent final approach CDFA or path over VS dive to MDA/DDA. Talks about CFIT too.
While not required,it does say operators should have a CDFA training program. The AC breaks it down into 11 training items. How many of us are getting that training? Here is the link.
