What I mean by favorite here is

"what I often find myself greatly admiring when I notice it's done really well"

gonna go with Director of Photography (cinematographer). with emphasis on the photography.

Some things I've watched recently that illustrate this role.

• Saltburn, great use of vertical space with the 4:3 aspect ratio, lots of color and natural light. Summer is captured well.
• Crash (1996), Lots of night scenes (always tough to get right), the setting looks appropriately dark, grimy, and mechanical.
• Fight Club, also a (literally) dark film and looks great.
