All I need is a good self-drilling screw (seems like most nowadays are) with fine threads, a length of about 2 1/2", and a head size (preferably washer head) of 3/8" or less. Is this a unicorn?
If you are going to plug the holes, couldn't you use a countersunk washer under the head of a 2.5" fine-thread drywall screw. The bugle head of the screw wouldn't fit the washer exactly, but that shouldn't matter.

Grex or McFeely both make world class screws, but no screw will self drill AND eject waste - which is what will result in the lateral pressures that will lead to a split. Go with a pilot, a split can occur as you drive the screw or months down the line and this will save you from the heartache.
I'm a HUGE fan of the Lee Valley kit with taper bits and countersinks, which together with Grex or McFeely eliminated my screw issues (I had 2 zinc screws break off and ruin projects which ruined my mood towards them forever...)
