dill which seems to be hated by most plants goes well with cabbage (and in pickling, too ;))
i read garlic does well with and for beans (but not onions)
savory with beans as well
basil and tomatoes enhances the flavour
that's kind of as far as i got.
will also have some marigolds and nasturtiums - for the bugs and for the flowers (i hope) :)
