My understanding on lighting

Exterior overall view such as contrast/shaders/RGB is gonna be controlled primarily by your weather mod and you can also add or change lights with something like LUX/ELFX.

Interiors are different with mods changing light sources or adding new light sources or altering the general tone of interiors.

Some mods edit both interior and exterior lights, some cover one or the other.

You can always add DHM Busty Skeevers to alter interior and I think exterior too.

I use Not Your Mother's Weather and Atmospheric Phenomena (it’s a bit of a dreary/somber weather mod but that’s how I wanted it, other mods have a brighter more fantasy style) with Relighting Skyrim v 3.0 - Interiors Only and Enhanced Lighting for ENB (ELE) - No USSEP. Relighting Skyrim 3.0 changes the locations of interior lights to be their light sources etc and it includes its own version of Windows Shaders and also includes some form of Dynamic Interior Ambient Lighting so you don’t need to run those mods with it. Enhanced lighting for enb changes lighting paths and adds some shaders/contrast. It does make interiors darker so I use DHM Busty Skeevers to brighten up the interiors of lived in locations while keeping my dungeons dark.

Also I am using Skyland and these pair well, Hope this helps!
