Always think about the teeth biting into, not away from, the finish material.
If you are using a circular saw: Finish side down, blade enters the back of the sheet, the teeth will be coming up into the finish face.
If you are using a jig saw, it will depend on the direction of the teeth on the blade. Most blades cut on the up stroke, so again, finish down, blade teeth rising into the finish face. The do also sell blades with the teeth going down to cut on the down stroke. These are most often used for Formica cutouts. If you did have one of those, you would have finish up to allow the teeth to cut into the finish face.
Routers and zip tools don't care.
If you do use any tool that touches the finish face, make sure you wrap the shoe with masking tape, scrap carpet, cardboard or some such. The vibration coupled with an aluminum sole plate or a used dirty plastic plate will mar the finish.

Also, finer teeth make cleaner cuts.
