Thanks for the suggestions, though for now i'll stick with vanilla. The UI doesn't annoy me enough to look for alternatives and i do like the voice of the voice actress, i'd just prefer it if it was more of a blank slate like the previous games - but they already decided to put a significant back story in there, so meh, whatever. Not knowing what my character will say doesn't bother me because doesn't matter what i say anyway :-P.
I did end up installing one mod though,
Fallout Accelerator, which disables vsync during loading screens to speed up loading times (they aren't as fast as FNV or even Skyrim SE - which supposedly runs on the Fallout 4 version of the engine - but they're way more bearable). It still has the 55fps lock during gameplay but over the years i've encountered *a lot* of physics bugs in games due to high framerates so i'll leave it at that. I do force 60fps through RTSS in many old games anyway to avoid such bugs, so it doesn't bother me.
