UE5 Lumen improve light and shadow quality + fix light leaks

Almost done tweaking my game level and I can’t seem to fine tune the lighting and shadow quality. Noise and overall quality of light and shadows as well as ambient occlusion are a bit off. I have a few spots where light is leaking under/side of the doors. I have a PPV that I’m using to try and fine tune these settings, but had no luck so far.
I should mention, all light is dynamic.

Any tips are greatly appreciated. See images below:
