The impact on plants and animals would probably the same of, say, an
extended rain season producing a year with less sunlight in some
region. The sunshade and aerosol projects are meant to produce a
global drop of at most a few percent in sunlight, and locally there
are much larger sunlight variations on Earth.

Indeed. But more often than not small deviations in one of the
dimensions in a multidimensional system does not translate in huge
deviations in other dimensions.
