I would only use 'main subject' when describing any group of works, and possibly genre if you have the data. Depicts, as I understand, is generally applied at item level - like an individual photograph, as a way of describing what is visually depicted in the image being described. You can also use main subject at item level to denote the main thing or theme depicted in an image.

These lands are connected with the London Township and Sombra Treaties of 1796 and the Dish with One Spoon Covenant Wampum. I respect the work of land defenders and water protectors as contemporary stewards of the land and support their vital contributions to the Earth and our society.
