Has ANYONE actually set-up various french drain configurations behind clear plexiglass (cut away-like an ant farm display) to see (for real) how it performs? In my 'minds eye', the possibility of collapse (despite the corrugations (I've seen crunched perforated pipe at the store!)) and the idea of standing water within the corrugations makes the flex pipe ...

It is very unusual (and usually obvious that it's NOT the case by inspection around the edges) for the floor to be in any way supporting the walls. Normally, it's footings, then walls, THEN floor; and the floor is not in any way tied to the walls. There are a few buildings with "bathtub" foundations, but they tend to be major projects floated (somewhat ...

Done right*, I have no concern for the foundation. I'd be worried that there's a pocket under the slab ...

The grating seems like the best solution. Not only will it increase the surface area of the drain, but also aids in cleaning the steps/landing because it can be picked up in one piece, taken to the top of the steps, and shaken off. However metal grating can be expensive, hard to work with, find in the correct size/hole size, and most importantly, will rust ...

Somewhat up to you, but standard practice (IMPE) is to cover the pipe with some rock, then fold the fabric over to "box" the pipe (overlapping the fabric, unless you want to get fanatical and seam it), then cover with more rock to keep it in place.
