Mesh Distance Fields for large indoor scene

Trying to get my head wrapped around Mesh Distance Fields.
They seem to have several uses and benefits but primarily used to increase the performance and quality of shadows in the far distance for outdoor scenes.

I am lighting a large indoor stadium scene with over 200 Stationary and Static Spotlights, and a Stationary Skylight. Target is Windows desktop only and am using a combination of baked GI and Ray traced Reflections, Shadows.

Would there be any benefit for me to use Mesh Distance Fields?
Also they are referred to as Ray Traced Distance Field Shadows. Does that mean Ray Tracing must be enabled for them to work?

No, there would not be any benefit for you.
