If something has onboard effects, it means it has certain sounds built into it, and you will not need to buy those effects separately. It doesn't require any extra wiring, as they're usually digital. Not all effects will be included. Typically reverb, delay, chorus, comp, and similar effects are included. They won't usually sound as good as stompboxes, but it's cheap and will usually get the job done.
