I'm assuming these are apps at the mac app store. Shop the productivity section and the Spanish apps. Get Keynote if you don't have it -the templates for presentations and brochures are novel to PC users, so it's easy to impress with the standard templates. Anything that will help you organize the hordes of pdfs, powerpoints, and study guides/flashcards you will be using will help. I haven't tried the software that reads to you, but I could see how that would be helpful for some people (listen while you work out, drive etc).
fyi: You don't need Microsoft Office to read ppts or send them. In case you didn't know, if you do a keynote presentation or pages doc, just click "export" in the file menu, and convert the file to a pc friendly format (word/ppt, but I usually convert things I do not want modified to pdf b/c most people don't know how to unlock them).
I've had a mac since I started med school, installed xp for M1 b/c my school has some software which was pc only. Haven't used PC for school since.
