Tracking Macros vs Tracking Calories for Fat Loss

I have always just tracked my total calories and I have had decent results but I am wondering if I should start being more specific with my macros. I keep hearing that protein intake is the most important thing for maintaining muscle while losing fat.

Does it really matter where the rest of my calories come from as long as I hit my protein goal and stay in a deficit? I find that some days I prefer more fats and other days I want more carbs. I am in Canada and I find my cravings change with the seasons.

Do you think tracking macros is worth the extra effort or is it just overcomplicating things? I am trying to find the most efficient way to reach my goals without spending too much time on my phone. I would love to hear your thoughts on this.
