The best thing to start with is to just wipe the painted surfaces down a very slightly damp cloth, and dry. I highly recommend a good quality microfiber cloth, like these, that I like because they are incredibly fluffy and soft:

Or use a chamois to dry the guitar (don't use the chamois wet like you would on a car, and don't use a sopping wet cloth, just damp). On the pickups and metal parts, make extra sure there is no excess water. Slightly damp works. Don't use a damp cloth on a rosewood or ebony fingerboard. You could ruin it.
Wiping down the guitar with a dry cloth will generally cause swirl marks. The dampness acts as a surfactant and prevents swirl marks from the wiping action. But it's ok to wipe off the fingerboard after playing with a dry cloth.
I think PRS may also make a microfiber cloth.
If there is grime, smudging, etc., try the PRS Guitar Cleaner. I spray a little on a microfiber cloth, wipe the guitar with it in sections, wiping it off with another clean one, or a chamois. It cleans well and leaves a nice shine.
The fingerboards rarely need anything. They can be cleaned with PRS fretboard cleaner or any lemon oil, but these are cleaning products. The exposed wood doesn't need extra oil. Rosewood is oily, Ebony is very tightly grained and your finger oils are enough. Maple fingerboards are infused with a finish. Just wipe off the grime, and dry the fingerboard. That's all that's needed. It's my belief that so-called fingerboard treatments are absolutely unnecessary except in the most extreme circumstances.
Polishes are for swirl marks and scratches. These aren't daily cleaning items. If your pickups and metal parts get tarnished, there are metal polishes that PRS recommends. PRS makes a polish I haven't tried, but if you have a nitro finish, do not use their polish as it's not recommended for nitro finishes. Make sure you get something nitro-friendly, like Virtuoso.
Although a lot of folks swear by soft all cotton cloths, microfiber cloths are actually gentler because the fibers are much finer than cotton, and they are less abrasive. Do this and you guitar will look new for a long time.
Unless you bang it into hard things, in which case, there's the PTC to fix that kind of stuff.
Avoid any cloths with nylon or polyester. These are harder yarns that will cause swirl marks. A lot of cotton diapers have poly or even nylon threads sewing the layers together, so these are worse than what I recommend.
