Hi Brad,
thanks for posting up the question. The three versions shown in Engel's book comprise the standard choices. As Engel and many others have noted, the housed dovetail is a weak option. If one goes with the housed dovetail then a reinforcing tie bolt is required to tie the beam horizontally to the plate.
The cogged lap joint is the best option, if you're looking for structural effectiveness. There are a couple of different versions besides the one shown in Engel's book, however what he does show is fine. Engel does however mis-name the cogged lap joint illustrated - it is not, as he calls it, a variation on kyōro gake, it has its own name and is called tsuki-watari ago
