My main concern with your question/suggestions is that you assume that questions that don't show any research efforts are fundamentally bad.
What do you think of these then: 1, 2, 3 and plenty more?
These could have been much longer had the OPs explained their failed attempts but to be honest, it would not have improved the questions which I find useful and straight to the point.
Based on your suggestion, they would be closed as "no research effort" if that were a close reason and I don't feel like it would be a good thing.
To conclude, I think that judgment is important in those situations and that the existing "too broad"/"opinion based"/"debugging question"/"Other" reasons are good enough for most situations where the lack of research is an issue.
