I do physical and digital notes both, just so that information is available in as many places as possible. I need a number to refer to a thing in an email? It's in a word doc, on a post-it note on my monitor, on my physical and digital calendar probably, and in a spreadsheet. No matter what, I can find the info I need.
And I feel like the actual act of handwriting helps me remember what I'm writing. I'll take notes during a meeting or a class, never look at them again, and remember the important info. If I don't take notes, I might as well have not been there lol.
