I don't play piano, but double bass and cello. A challenge that I see is that a great deal of sheet music is still not available in computer readable form. So there's no data, much less labelled data. And the pace of introducing new material is painfully slow.

A problem may be that once fingering becomes intuitive, then there's no incentive to write it down, and you might not even be able to articulate why you chose a particular finger.

I only think about it when I'm trying to work out a difficult passage, and then I'm usually thinking of intervals and shifts that afford me the best chance of playing in tune. Fortunately that's not an issue on the piano, but the idea of finding an ergonomic and less mistake-prone fingering is probably a similarity.

On the other hand you might be surprised at how little it might cost to have a pianist or piano student number some music for you. At least on cello and bass music, when material has fingerings, they only need to indicate the ones that are non-obvious.
