First: You have to kill the boss node flagship enough times to blow up the map HP bar. S-rank is not required, just kill the boss node flagship. Every time you kill her, the map HP bar drops a bit. Only when the map HP bar blows up will you be able to go to the next map. The number of required boss kills to clear the map may differ by difficulty chosen.

Second: Every time you change difficulty, the map HP bar resets. This means that, for example, if you are ready to start the last run on the map (meaning that the boss node flagship needs to die once more to clear the map) and if you change difficulty, the map HP bar will be reset and you have to start all over again. This is useful for farming the boss node for drops before actually clearing the map.

Third: I don't know what you mean by "no difficulty mode bonuses". The difficulty you choose affects what enemy compositions you'll find, as well as the reward you get once you clear the map. It may also affect the drop rates. That's it.

Also, once you clear a map, it will lock to the difficulty in which you cleared it, so keep that in mind if you wish to farm drops.
