The overnight soak has become unnecessary since canned organic beans of several kinds are on the supermarket shelves. The brand I use has only the cooked beans and a little sea salt. No preservatives, no flavorings. Cans are only 398ml, so two are needed for most recipes.

The black beans we use are not organic, a brand called Primo (put up in Toronto), and have only salt added. Safeway black beans only have salt and a little calcium chloride added. Both come in 19oz (540ml) cans and are very good. I'm sure there are other good brands.

Over the years we have tried several brands of canned baked beans and found them all poor. Adding ham or bacon helps, but the seasonings are peculiar.
On camping trips, we have tried several brands of chile with beans and/or meat. OK in the camp but unacceptable at home.
