Regarding the PDFs - I will look into that. I think I always assumed if someone was reading on a smaller screen, an epub would suffice, but I shall see what I can do with the PDFs.

If it helps to understand why someone would stick to PDFs: I want to both preserve my ebooks over the long term (decades) and annotate them - comments, highlighting, etc. ePub's format is less stable for the long term, but most of all it lacks standardized annotation (afaict, after some detailed research). Also, if I annotate a book on my computer, I want the same copy on my small screen.
I have the old remarkable and use it without its cloud features. Even though, according to its documentation, it's supposed to be able to handle EPUBs, I have, for some reason, never gotten them to work.
I have also kind of "standardized" on PDF for the way I manage my own collection, because you can always make EPUBs into PDFs, but not the other way around.

I hope that's helpful!
