Digital does not normally take a fixed preposition. Words like in, for, and by usually belong to the larger sentence, not directly to the adjective.
Digital is usually used directly before a noun, such as digital media or digital tools. Phrases like digital for education or digital in healthcare are possible because the preposition introduces purpose or context, not because digital selects that preposition.
These forms are not interchangeable. Choose the construction by meaning, not by which preposition appears most often.

In often introduces the field where something digital is used or discussed.
By sometimes appears in larger expressions such as digital by default. The preposition belongs to the whole phrase, not directly to digital.
