I was having difficulty understand how DOF can be affected by other camera settings and found this video which helped a lot - https://www.youtube.com/watch?v=34jkJoN8qOI&ab_channel=DylanBennett
TLDR; it's affected by 3 things: focal length, distance to subject, and aperture. It really helps to draw it out to see why, but basically:
distance to subject up, DOF up
focal length up, DOF down
Aperture/Fstop up, DOF down
The video uses a "toothpaste analogy" along with drawings to help explain why. Although it didn't mention how sensor size can affect DOF, I suspect that if all else were equal then an increase in sensor size would decrease DOF as it would have a similar effect as reducing the focal length.
