I have used 3/4" dados 3/8" deep on 3/4" AB plywood that held together very well using glue and finishing nails driven down at an angle.
You could always use screws and countersink with plugs.

Yup, fastener reinforced Dados and Rabbets are your best bet.

Good router based dado jig plan HERE.

Patrick (GulfcoastGuy) is exactly right! Ive been using a jig like this for many years - and have never had a problem cutting dado slots perfect every time! I will say this, though; although it is unavoidable - I despise using fasteners into the end grain of plywood. There is a work-around which is to predrill a small diameter hole for the fastener (through the ungrooved side and into the end grain), then drill another larger-diameter perpendicular hole downward for a wooden dowel. Carefully planned, this enables the fastener to go into long grain of the embedded dowel - screws are preferred over nails. Trim the protruded ends of the dowel after the fastener is fully seated.

Here's an example of a rabbeting bit from Freud. Note the interchangeable bearings for different widths. However, dadoes are preferred if maximum strength is an issue.

Buscuts have worked well for me as well as a spline. They're solid and as long as you index both pieces from the same face they'll be flush. I then place wax paper on the plywood faces and put on a call and clamps to keep the jount centered. Nice to read you're working with your Grandson.
