I don’t have a good resource, but min, max, minmax are good if you have a responsive layout where elements change (under a parent container in vh, vw, %) but you also want to have a threshold that is not exceeded. Like min-width or max-width, but as a value instead of the explicit css property, which means you can set properties to equal that value.
Thanks. After reading your explanation it became clearer that the reason you use clamp is because you're using different units (e.g. rem vs %, px vs vw) and varying page dimensions may affect those units differently (e.g. 10% may be larger or smaller than 100px depending on the parent's width).
Here I read the entire MDN article on clamp and it didn't click in my mind until you explained it.
MDN has some good explainers: https://developer.mozilla.org/en-US/docs/Web/CSS/clamp
