These days, when I go out I leave with body and one lens only. I make that decision before I go considering where I am going and what I want to photograph. I do this because it keeps me focused on what the photography itself and not gear choice paralysis.
Some bodies are more flexible and that may give me two focal lengths. The D850 is such a camera body. A 24mm on it is also a 36mm. The 50mm is also a 75mm.
I have no hesitation whatsoever to use both focal lengths. But I generally prefer just the one focal length. For that reason, I prefer taking the D500 if I know I am only going to use the 36mm focal length.
I prefer to keep it simple.
