All my pads are Lake Country (LC)
But I have three different types. There is the CCS (Closed cell system), the flat pad and the hydro tech pad. Each type of pad has a range of choices for softness/agression. I have yellow, orange, white, red & blue pads in all three types.
Each pad has both a thickness and a diameter than can effect how it works. Smaller and thinner pads tend to be more agressive while thick and large diameter pads tend to be less agressive (relative to the same color smaller pad).
I recommend getting six pads to start - three with medium agression (orange for Lake Country) and three with little to no agression (red or blue pads for lake country). For the FX35, you will use one pad for two to three panels of the car before you need a fresh pad. You can periodically clean the pad during polishing to keep using it but it's just a ton easier to use a fresh pad and then wash them all out after you are done, rather than try to make one pad last for the whole car.
Medium agression pads are more than enough to remove swirls - especially when coupled with the right polishing product. The red/blue polishing pads are best for waxes and sealants - if you plan to apply by machine. There's nothing wrong with applying the wax layer by hand with a hand applicator instead of the machine but for paint correction - reducing swirls or light scratches - you need a pad/product with some cut to it.
