If you don’t plan on going through the bag during your trip then try a backpack. I have this one and like it a lot: https://a.co/d/0udpWoH

If you’ll be going through the bag during the trip for your coffee or a book or whatever, I’d do a cross-body bag. Going in and out of a backpack more than once is a pain. Baggallini is a good brand - maybe something like this? https://www.baggallini.com/the-only-bag/OOB760-BG.html

Browse in TJ Maxx/Marshall’s and I’ll bet you’ll find something.
