A photograph is not merely about what is in focus, within the Depth of Field zone...How blurry will the out-of-focus areas (outside the DOF zone) be?
Compare combnations of f/stops/FL in a single graph...the standard chart starts with two scenarios, but you can add more scenarios which add curves to the graph. 'More blur' is a curve that goes higher on the graph, 'less blur' is low curve along the graph.
You can widen/narrow the range of distances for which the blur graph is depicted, and change the framing of the subject from thight headshots to very wide framing.
This example shows a comparison of using three differen FL at different apertures. At 10m behind the subject, the shortest FL has the most bur, but about 1km behind the subject, the three combinations are actually quite similar in degree of blur.
