What foundational Resolve node structure reduces chaos in grading?

[Joshua_P]

I'm a freelance videographer transitioning from basic correction to developing a consistent, signature color grading style for my documentary work, but my current workflow in DaVinci Resolve is chaotic and inefficient, leading to inconsistent results across projects. I start with a technical correction but get lost when trying to create a specific mood or look, often overcomplicating nodes and ending up with muddy shadows or unnatural skin tones. For colorists who work on narrative or documentary projects, what is your foundational node structure and workflow for building a grade from the ground up in a logical, non-destructive way? I'm looking for advice on how to separate technical adjustments from creative looks, use power windows and qualifiers effectively without making things look processed, and how to manage your time when you have hours of footage to grade under a tight deadline.
