Congrats on making the change! I'm with you- cc'ing is the easiest, most flexible, and intuitive weight loss method (for me! everyone is different) and I hope you find the same success with it.
I first started only looking at calories until I a) got the hang of it and b) started slowing and stalling in my weight loss process. That's when I felt comfortable making other changes- for a while adjusting my fat/protein/carb ratio first, then a month or so later looking at fiber and sugar. For me it was good to just take a few things and start adjusting them rather than try to keep up with everything all at once. It would have been too overwhelming. I'm now able to mentally decide what combination of foods I'll eat during the day, or readjust dinner based on lunch, to meet all my own different nutritional goals. It has taken several months to get there, and for me working incrementally on one thing before adding another has been better.
I would do whatever you feel comfortable with. Ideally it's best to get in enough protein, lower your sugar, etc not just for weight loss but for overall health reasons too. But don't feel the need to hit perfect numbers on everything immediately- making one change at a time is still moving one step closer to a healthier lifestyle! All of us are always improving, one step at at time
