I think we see examples of both outside the movies:
The paper meme came from the first edition of the RPG, changed to 'rarely used' in the second edition. I think the EU had an example of someone using paper and someone else commenting that that was strange but the details are fuzzy. We see paper books in Rebels as well but I think the implication is that they (and obviously, the sacred jedi texts) are extremely old and predate digital storage becoming the norm.
As for other culture... Flight simulators seem to be described as roughly analogous to video games in universe (IIRC your family members in x-wing alliance are critical of you for spending too much time in the simulator as a kind of in-joke) and you also have the holo-chess... Then there are the skeevy guys watching a tei-lek dancer hologram at Saw's hideout, presumably there's some kind of holographic entertainment industry, since they're ubiquitous enough in Jeddah city alone for the imperials to hijack them with missing cargo pilot wanted posters...
Then there's Chass na Chadic in Alphabet Squadron - she maintains a collection of banned holos, poetry, and other media which she barters for banned music: she likes to rock out in her b-wing. In her case she selects her playlist by picking individual chits with individual songs on them, which may be a limit of the storage medium or else an artifact of their illegal underground distribution.
