All street pads should be bedded to reach max. performance. New rotors need to be cleaned before installation so the corrosion prevention on the rotors from the factory is not transferred to the new pads. If the rotors have a coating like zinc, the bedding process should be delayed until the rotors are shiny.

There is a bedding process to transfer pad material to the rotor and to seat pads to the rotor. Pad material to rotors takes 10 or so moderate stops from 30-10 with a half minute gap between stops followed by a cool down period. To seat the pad to the rotor takes 5 stops from 50 to 10 and a half hour cool down.

IMO turning a rotor is a thing of the past. Rotors are thinner than the good ol' days and much cheaper and in the case of BMW are not designed to be turned. If you do turn the rotors it is a good idea to go through the pad to rotor bedding an extra time.

The biggest benefit of ceramic pads on the street is less brake dust.
