How did everyone end their Fallout 4 story? For me I did the Minutemen ending with them controlling all Settlements. The BOS is a primary Ally with the Boston Airport Settlement serving as a trading hub depot from Diamond City/Minutemen Settlements. I kept the Railroad alive based upon my decision to spare Danse, with Jamaica Plain serving as the lone Railroad safehouse. Preston is the Minutemen President with Sanctuary serving as the Capital & Covenant as an Embassy. Due to killing Mayor McDonough Piper is made acting Mayor of Diamond City. The Railroad is left to send synths to Arcadia while ceasing guerilla operations against the BOS, otherwise they'll face termination from the Minutemen/BOS. Deacon decides to take on the alias of the Silver Shroud acting as a vigilante in Goodneighbor. Nuka World/Far Harbor are protected by the Minutemen as an alliance is formed between the Habormen & Traders. Meanwhile with the BOS all pre war tech/technical documents found by the Minutemen are turned over to scribes and paladins. Gunners,Ferals & Super Mutants continue to be a threat however military checkpoints and vertibird patrols are able to keep the Commonwealth safe. The Commonwealth's peace is sustained long-term for the Minute to establish several forts with a united Government allied with the BOS. The Brotherhood continue to expand their operations bsck west and even back to the capital wasteland while the Railroad eventually retire.
