Here are my basic lamp Evee and Cycles light setups.

Evee
I noticed in my Version of Blender, 2.91, I that I could not adjust the shadow softness. There is an option in the render settings, but it is only a tick box rather than a scaling bar. It seems that I must either have too soft of shadows, or have a cartoony abstract shadow. But the second option does not bother me, I kind of like it.
