I think it's a bit pointless to generalize about finger patterns like that, because the pattern depends entirely on whatever musical figure you're playing.
I agree with that thinking.
I am mostly a finger picker on guitars, banjo, lap steels, etc. I grow my own picks at the ends of the fingers (and I do play keyborards too, so I hear you on that). I use all four fingers and thumb. I've spent nearly fifty years getting all the fingers equally strong and independent. That's what God gave me, so I might as well put 'em to use. I tend to use the thumb, index and pinky most (don't know how that happened and don't care). I don't analyze or dwell on prescribed techniques. I feel it gets in the way of playing. I teach the " do what works for you and feels comfortable" method. Concentrate on the tunes and it all works out.
Now, to be fair, I play lots of music on different instrument and in different styles. So it is in my interest not to concentrate on a particular technique related to a single style. In the case of what you have posted it seems to me that keeping the strong beats strong is what matters.
