There are no hard rules on what goes where but there is a general convention that Depends is for vital things, Recommends is for "standard" user-level things, and Suggests are totally optional.

>>> I think when installing all Recommends, the doctests should pass (as during build). So I'd put cython/sphinx in Recommends. I find Suggests a bit useless because it's not installed by default and I don't think that many people look at this to get ideas what else to install.

As concerns singular-doc, it is only suggested by the singular interfaces.
But if I remember well, SageMath needs the singular.hlp  data file, which is distributed by singular-doc .
