what challenges arise in parameterizing this function for different materials, and how computationally intensive is it compared to using a BRDF?

Is the scattering of light done arbitrarily or does it depend on the type of material it penetrates through. My intuition leads me to believe it does depend on the material because you can make something look softer if light is able to scatter equally in all directions, where as something would look sharper if it runs into micro ridges

How do you determine what scattering functions would match some material property? Is this something that we know how to compute through optics in physics, or do we just try different functions until the look of the object matches the look of the material we want to render?

I've heard about scattering as it happens in skin, and I wonder how much more time it takes to implement something like this, and if there are other ways to 'cheat' and make it faster

How are we able to determine the exact path light can take while inside of a material? I feel like materials are not always consistent in terms of their internal structures and because of this, the scattering of light that occurs may vary quite a bit and may cause different samples of the same material to look different.

What is the difference between BRDF and BSSRDF? Which should be used in different scenarios?
