I have not found anything like you are asking for for I have asked myself the same questions.
Being of a theoretical background I naturally have a theory on it which I might well pose at some point.
I think with eyepieces there is a lot of subjectivity hence it is hard to get definitive answers (everyone's eye is different and there are different desires when viewing).
Regarding planetary - if you want detail etc then go back to basic designs and for me it is orthos.
