I haven't experienced layer adhesion dropping with higher nozzle sizes. Are you setting volumetric flow rate limits? If you don't limit the volumetric flow rate, and try to run higher nozzle diameters at the same speed as smaller ones (especially with greater layer heights), then this could cause that issue, because you're extruding material that isn't adequately melted. But in general, nozzle diameter and layer adhesion shouldn't be closely related.
Minimum feature size, on the other hand, is definitely related, and is indeed the main reason you might want a small nozzle or low layer height.
