Thinking about problems; When to use a large depth of field and when to use a small depth of field?

The depth of field is a clear range.

When you want to highlight something or a part of something in the picture, you need a small depth of field. (large aperture)

On the contrary, if you want the scene in the picture to be clear from near to far, you need to use a large depth of field. (small aperture)
