Both forged and cast can be, and most often are, machined (cnc or otherwise) as part of finishing off the product. Both leave pretty nasty looking surfaces. It is normal to cut at least the mating surfaces back into the better material in the interior, so that these surfaces are smooth, clean, and true.
Cast or forged does not result in a finished part that is ready for assembly.
Most of the benefit of casting is in reducing wasted material and the labor involved in cutting that material away. Casting provides a piece that is much closer to being finished, but it still has to be finished so that it can be used.
Forging provides a similar jump to a piece that is already roughed out and closer to finished, but the process yields a piece that is structurally stronger.
