I am trying to drape a cloth onto a floor with gravity.

I tried giving your solid a bit more extrusion thickness (it was 1) and works like a charm:

Thanks. any suggestions how I can get this to appear more like a piece of cloth or a rug on the floor, with slight wrinkling?

I would insert a Grab (that allows you to drag Kangaroo mesh vertexes directly with left mouse button on the Rhino window), a weavebird subdivision (to make the mesh a bit more soft), and a 0…1.000 number slider as input to the Z force
in such a way you can set Z strength to zero, wrinkle the cloth by hand, activate a bit of z push again to let it fall, wrinkle again on so on:

I think increasing a bit the cloth-mesh definition would give you better result

this is ten million times better than my above one
I completely agree that for simple things like a panel with a slight sag, there’s no reason to simulate for visual purposes. Also I expect that the finer wrinkles and creases in the fabric in the first images posted are just a good texture or bump map.
For more complex folded fabrics though, I think I’d struggle to make it look realistic just modelling manually.
Anyway, here’s another example with some draping over solid objects.
