Raster -> Analysis menu entries are from gdal tools, and can be expanded by using the command line options that are available. See the GDAL manpages for details.

In addition, the processing toolbox offers the GDAL tools too, and GRASS and SAGA routines for slope and hillshading.
So plenty of possibilities to get the style you want.
