contact hardening and cascades are the most expensives options and definitely not meant for integrated or mobile gpus.
If you mean by “self shadowing” an object that can shadow itself, it’s a “given” of the shadow map technique (as long as you set the object as a shadow caster), there’s nothing specific to do about that.
PCF and PCSS are filtering techniques that helps to soften the edges of the shadows:
No filtering:
With PCF:
You can either use PCF or PCSS (or None, as in the first picture), but not both at the same time.
Holy Crap Nuts !!!

And exporting using Unity Mixed Lighting Options
Looking sweeter and sweeter
