I've used the 3 above for a long time. Project Valkyrie is from the same author. https://www.nexusmods.com/fallout4/mods/28085 Lima Detachment https://www.nexusmods.com/fallout4/mods/29042 Sector V https://www.nexusmods.com/fallout4/mods/38457 The Bleachers https://www.nexusmods.com/fallout4/mods/40267 Sequel to The Bleachers is The Fens Sheriff's Department. It contains The Bleachers and goes much further. It can have some issues, read some of the comments on the mod page to see if you want to tackle it. I've run all these together without any functional issues.
Open bodyslide. Select the outfits you want. Select the CBBE Zeroed Sliders preset. Build the outfits. They should then conform to whatever body shape you're using. A fellow called Gopher on youtube did a great video on this. I'm not sure if we're allowed to link to other sites here but it shouldn't be hard to find.
The recommendations here https://www.nexusmods.com/fallout4/mods/41435 are solid. I haven't used everything listed but those I have used were trouble free.
Where do I find Fusion City's companion tracker? If you have Fusion City Rising installed it should be in your inventory. If not it can be crafted at a chem station under utility. Look for FCR Companion Locator.
Lima Detachment, The Bleachers, Outcasts & Remnants, Project Valkyrie, and Depravity. Operation Manhattan is pretty good too. Should get you several more hours of gameplay.
Just a dumb comment here, but have you enabled the menus for sim settlements? This has to be done with, IIRC, settlement menu manager, or possibly the city planner holotape. I don't use UFO4P so can't offer any suggestions there.
I've used both Scrap Everything and Spring Cleaning. Both were OK but cause some other issues. After several playthroughs I really found scrapping to be tedious anyway. I use https://www.nexusmods.com/fallout4/mods/25350/?
