I get a good result combining one of the Nova Luts with GITS Fuji, (though I see the GITS I used is currently temp hidden on Nexus - worries me. This version is still available but watch the game version). GITS comes with the weather ENV, so Nova handles only the LUT. I didn't like Nova rain anyway.
There are several Nova LUTS so it's worth experimenting with the Nova/GITS mix you like. The author has done quite a few. Classic and Pure are both good. I use HDR on a 21:9 OLED 4k monitor.
GITS really brings out the Nova LUT image with contrasts and weather. I use Path, Ray Tracing, Framegen. Path Tracing is an FPS killer BUT makes the game look excellent. I have to compromise to save my FPS. I run a 4080 Super but an i9 processor. In the Game Settings, turn Screen Space reflections to Medium to save a bit of FPS.
You can also pop in some of the nice HD reworked textures available.
To keep performance up I use this mod and choose the PT21 and the Balanced presets in the on-screen menu. I believe I added the Bright and Colourful Reshade for Nova to make it pop a bit.
Here's a screen from mine, though I confess I mucked about with it a lot since I took it.
Have fun!
