Nting that I haven't tried the Sonus pads or most of the products on your list, I'll try to at least point you in the right direction.
The general idea is to match the cut of the product with the cut of the pad so they're working in synergy, as opposed to having one (the pad or the product) compromise the other. If in doubt, use a milder pad.
For waxes and other nonabrasive products you want to use a pad with no cut. Finishing pads are the obvious choice, but many polishing pads are also soft enough for this and I generally prefer a pad that isn't *too* soft the way some finishing pads can be. Some of the super-soft finishing pads load up with product and compress too much for my taste. Don't know how the Sonus ones (IIRC they're blue) will work out but try one and see. I'd guess (from inspecting the blue ones, but no actual use) that they'll work better than some other finishing pads I can think of.
If the Deep Crystal carnauba is the liquid I'd consider using that with a very soft pad, oughta work fine.
AIO I'd use with a soft polishing pad, not a finishing pad, for the reason stated above.
Most light polishes should also be used with a polishing pad (with Sonus that's green or white IIRC, but I'm not certain). I'd rather use a sorta-aggressive product with a mild polishing pad than a mild product with a sorta-aggressive (light cutting) pad, but that's just me. So if you want to try Scratch-X by machine I'd use the polishing pad for that too and ditto for the SFX-2 (but I'm really guessing there as I haven't tried it- it *is* an educated guess though

).
Cutting pads I reserve for use with aggressive products and I assume I'll have to follow up with something on a milder pad.
