I started with Simandl fingering (1,2,4). Around 1991 or so, I started transitioning to OFPF. I think the reality is I use 1,2,3 that vast majority of time, although certain patterns benefit greatly from adding the pinky. Extensively using 2,3,4 is more taxing and less accurate for me...so I don't think your problem is unusual. Learn to use the pinkie when it is beneficial...and learn to not use it when there is a better option.
I think I have a system (or perhaps multiple systems), but I have not really codified it/them. I just sort of play. Sometimes I stop and think/work out how I will play a certain technical line. I think mostly in terms of which finger will hit the note, and to a much lesser degree where the shifts occur.
There are some patterns (particularly repetitive minor patterns) near that nut on the low strings that are really hard on my hand and wrist with OFPF. There are multiple factors: distance of reach to the nut, angle and rotation of wrist, spacing between frets, reach across a 6-string fret board, etc. I can play these lines most cleanly using OFPF, but it's very hard on my wrist, so I sometimes revert back to Simandl.
You can use all four fingers without using OFPF. The idea is to use microshifts to avoid overextending the spread of your fingers.
