Hi. There may well be other tutors who strum with their fingers, but Caren Armstrong is the person I see using this method most. Here's an example: https://www.guitartricks.com/lesson.php?input=18320&s_id=1408. Caren has her own section on the instructors page with loads of songs. I've only tried a couple of Beatles songs - Yesterday and Blackbird - but both are hand strummed . Hope that's what you're looking for.
