Macros Percentage?

Macros are pretty much personal preference. Nothing wrong with starting with the mfp defaults. Many of us look at the protein and fat numbers as goals to exceed and let carbs fall where they may. As you log, if you start to see a pattern where one macro being high or low affects your appetite or satiety, tweak your goals. Most people find one or some combo of protein, fat, and fiber filling.

Welcome and good luck!
