Where the fastenings won't be seen my technique is: Dominos or biscuits to align the box parts. Crown staples to temporarily keep the pieces pulled together, than 1-1/4" to 1-1/2" screws - with glue. If I use the dominos for alignment I skip the crown staples, but biscuits are a more sloppy so they need a little back up. Prefinished plywood parts don't lend themselves to glue (unless you get into urethanes or epoxies which I won't do for cabinet construction.)
Admittedly my boxes are rather overbuilt - you can drop them off a speeding truck into traffic & they will fare pretty well. (Don't try this without adult supervision. My mommy won't let me do it, so I 'm only guessing :-\.)
Face frame parts are pocket screwed & glued together, then the fully assembled frames are biscuited to the carcass. This is a case where the alignment of the dominos is way too perfect. You need the side to side sloppiness of the biscuits & the little rocking that they can do front to back in order to help with locating the FF accurately. Sometimes you need to square the box up a bit & being able to rack the assembly before you hard clamp it is very useful. Dominos don't want to play that game. Of course there is lots more to it than this brief summary but to the original post - 'nuff said.
