I will try to answer your questions.
The reference to "undisturbed soils" is not a local term or usage. It is possible to form footings above grade on undisturbed pahoehoe but since you have had your lot ripped and leveled that is not an option.
You will be needing to import base course (gravel and fines) to further level and compact on your site. You may or may not need to compact the ripped site prior to this. Your issue will be settling of substrates after the slab is poured and building up.... you do not want settling. DO NOT base your slab with cinder. Waste of time, waste of money. Not legal. You would need to remove any cinder from the house pad which is not as easy as putting it in. Cinder is not competent material.
As for block wall vs.PIP for stem walls..... that is matter of preference and the skills and experience available.
I do like to remind people that the building codes are only the LOWEST standard of construction allowed by law. The codes are not instructions for how to build your home.

Assume the best and ask questions.
