Last time i played this game, the port/lab didnt exist and the abandoned factory didnt replace the pine woods :(. my main goal is to get a drone cuz settlement lame :)
actually as someone who ignored settlement and went for the drone and transport hub i can tell you that you definitely should not ignore settlement at least unlock the substation and every building level 2 and walls level 3 because that way you'll have a much easier time fixing the bridge and unlocking mods for your drone
