There are also centrist doctrines. Even explicit ones like the radical centrism.

A major problem is trying to project a hugely multifaceted phenomenon like political outlook into one, or even few, dimensions. And then even discretizing the one dimension. And then categorizing (other) people's thinking or ideologies into these.

Another problem is assuming that there is some universal "optimal" or even good policy. Instead there can be even fundamentally contradicting interests or goals between e.g., dare I say, classes which can lead to well informed

I'm not claiming you don't appreciate these, but the conclusions to me seem to require such problematic assumptions. The intent is likely something like trying to simplify complex phenomena into something manageable (i.e. an ideology), but these tend to be very leaky abstractions.
