Is there a typical 'ferrite' for use in a PCB?
No, there isn't. Each ferrite has its own characteristics and curves, and selecting the correct ferrite involves examining them and seeing how they interact with the system. Sure, there are a wide range of things you want to filter across a large number of circuits, but a ferrite large enough to do so is too large to belong on most PCBs (which is usually why they're on the cables leading in and out instead).
