Dolomitic limestone contains both calcium and magnesium, so it would be the best choice if you need to provide magnesium in addition to calcium. Finely ground limestone would also have a relatively rapid reaction with the soil compared to coarsely ground limestone, but this was not specified as a top priority in the question. The other options (low shipping cost, high soil pH, and reducing exchangeable Al³⁺) did not mention any specific preferences for fineness or dolomitic limestone.
