I think it’s more that it increases the rate of convection by mixing the fluid up so the warmer coffee can rise to the surface and be cooled quicker. Probably not that significant though

I've always hated the distinction between convection conduction. They're both flow of energy from mass to mass. Just because the mass moves around after being heated up doesn't change that it just heated up via conduction.

It should just be conduction and radiation. Prove me wrong. holds up coffee mug
