This is a list of series that I'd classify as "moderate" H&E.

This label doesn't communicate any specific content of the series themselves - they're not "moderate" in terms of ecchi content - but moreso that these series tend to lay in the middleground between traditional and progressive sensibilities. They can feature many pronounced traditional H&E elements, while having key components be portrayed in a way that could be labeled as progressive, or vice versa.

These are your centrists on the spectrum. They don't radically depart from the norm in any way, nor do they fit the mold of a traditional H&E. They're tweeners.
