First off, the objective is to make box joints. To be clear on the
definition, this is a box joint:
Here's a nice howto on making a jig for a handheld router:
He doesn't show it with the pieces stacked, but the principle is
fairly straightforward. Same technique but clamp together all the
pieces that get the same cut and do them at once.

The objective is to make drawers strong enough, fast, and cost
effective. In that order of importance.
Board lumber (other than general rough construction lumber) is expensive
locally so it could be self eliminating over ply. There are no "real"
lumber yards left around here. Just construction lumber yards who, "can
get that for you, but it will be expensive." The last guy with tons of
good stuff actually was across the street from my old office. About the
same time I went over to see him about some stuff for a big job he
retired and liquidated everything. He didn't have anything I needed
left. Just my luck. LOL.
Not sure who made the comment about gluing end grain on plywood, but
um... only half of the end is end grain.
One thing I noticed is a lot of the guys (on YouTube anyway) doing
pocket joinery don't seem to be using glue. When I have glued and
screwed ply in the past (not pocket joinery) I used lots of glue. The
combination is pretty darn strong and doesn't seem to shift, tweak or
flex much. Ply is also pretty stable.
By the way I do know what a box joint is, and I got the message about
stacking the first time. Jim is more of a metal worker than a wood
worker like myself. You are more likely to see him hanging around R.C.M
I've no experience with making drawers for holding hundreds of lbs. of
motors and such, but, I absolutely would not simply use Titebond and
pocket screws with plywood. Pocket screws are not appropriate, imo, for
any drawer and gluing plywood edge grain to face grain is also a no no
in my book, especially if strength is an issue.
Personally, I wouldn't even use plywood, I'd use 1x material with at a
bare minimum of locking rabbited drawer joints and glue. No screws
needed but could clamp with nail gun for speed while glue dries. This
would be very fast for multiple drawers of a standard size on just your
table saw, and way stronger than pocket screws, glue and plywood.
Also it's worth noting that drawers do not need to be the full height of
the drawer opening. The drawers mainly just need to keep the items from
rolling off the drawer. You can save a lot of material with 100 drawers
that way. Use plywood for the bottoms.
Tolerance is the virtue of the man without convictions.
