I find with difficult Bach I need to get good at each fingering before I can render a decision. That means hours learning each one (for me).
This accurately reflects my experience. Left-hand fingering is difficult. There can be many possibilities for each beat and unless you have to play F or F# on the sixth string, the possibilities and combinations are nearly endless. In addition to what finger to use, there is the issue of what finger to use as an anchor, when to remove each finger, when to slide the same finger to the next position on the same string, which finger to use to guide the slide, when to use a finger as an axis, and so on and so on.
Amayo's Metodología de estudio para la ejecución e interpretacíon de la guitarra clásica
is the only book I have seen that discusses a systematic methodology for left-hand fingering. I recommend this book unhesitatingly, because it is freely available on the internet and discusses many issues in detail (left-hand fingering, interpretation, phrasing) that every guitarist needs to know and that I have not seen discussed elsewhere. Amayo advises letting your teacher guide you on the left-hand fingering, but that will not work for everyone.
