How to set the optimal standard of Nikon D750 shooting landscape?

I am also shooting scenery with Nikon D750 SLR. I haven't optimized the settings yet. White balance is automatic. I shoot in RAW format, and I can adjust it according to my favorite effect later. In addition, all the landscapes I photographed are equipped with polarizers, which can make the sky bluer and remove the reflection of water, metal surfaces and leaves. These are just some of my ways of taking pictures of the scenery, for communication only.
