 Sonia Roca-Royes and Bob Fischer both take a modest approach to the epistemology of modality. Roca-Royes (2017, 2018) divides the space of epistemological investigation via the ontological distinction between concrete and abstract entities. In a 2017 work she offers a similarity-based account of our knowledge of de re modality for concrete entities. And in her (2018) she offers an account of modal knowledge for abstract entities. Fischer (2017) divides the space of epistemological investigation via a topical distinction between ordinary and extraordinary claims.
