Of the five series, DS9 and Voyager are the two that basically "finished their stories" during the course of their runs. TOS, TNG and ENT (less the last future set episode) continued their adventures.
A Enterprise movie could be set anywhere during Archer's time on the ship, after Broken Bow, outside of the Xindi arc and prior to TATV.
