I make no pretense that this is a "best practice" but this works for me using Calibre to transer ebooks to my devices:

In Calibre my metadata "Author(s)" and "Author sort" is Lastname, Firstname.

I use "korbooks/{author_sort}/{title:shorten(50,_,0)} - {authors}" as my send template to keep file names a reasonable length.

All ebooks go into the same folder. My "Home" folder is therefore sorted by author Lastname, Firstname with ebooks in their appropriate author folder.

I use filtered Categories to separate epubs from pdfs, etc. My collections appear to "Arrange" properly by either "Authors" or "Title."
