Heck, Sanctuary got annoying to me since it was always “There’s some ghouls that have been bothering us and we might get overrun.” I gave you all combat armor and plasma rifles plus put tons of turrets around this place. You’re gonna be fine.
edit - as a sidenote, there’s a mod for Death Trooper (from Star Wars) armor, helmets, and rifles. If you have the inkling, setting up settlements with Imperial Troopers is both kinda fun and also excuses their horrible aim. And yes, it includes the red bolts and iconic sound effect ;)
PS - one more minor rant/fix. Want to get rid of dead bodies at settlements because it’s kind of freaky how comfortable settlers are sleeping in rooms with dead ghouls, etc? On a PC, go into console mode, left click on the corpse, type “disable” without the quotes and hit enter, then type “MarkForDelete” without the quotes and hit enter. They’re gone forever. You may want to save beforehand in case you delete the wrong person, btw.
