Volumetric Fog experts

Hoping any Volumetric Fog experts can chime in.
Simple large indoor scene, no Raytracing, a Skylight set to captured scene and a couple dozen Spotlights.
Additionally Exponential height Fog with Volumetric Fog enabled and PP Volume with manual exposure.

Goal is simply volumetric fog rays from Spotlights and overall fog ambience increasing with distance.

Using Luoshuang’s GPU Lightmass because I’ve found the quality of lightmaps better.

Looking for good project templates I can reference, tips, suggestions on how to consistently achieve high quality results. Light mobility settings pre and post bake, console commands, etc etc.

I’ve played with settings and permutations for a couple weeks now but still nowhere where I want to be in terms of consistency and quality!
