I'm worried about losing volume due to facial sagging. What kind of procedure should I get?

Recently, whenever I take photos, the center of my face looks a bit sunken, and my nasolabial folds are more noticeable than before, so I am looking into filler treatments. In particular, perhaps because my front cheeks lack volume, my face feels longer overall, so I am considering consulting about both my front and side cheeks. I searched for filler inquiries regarding nasolabial folds, front cheeks, side cheeks, and forehead for a full face, and I learned that the required amount and design vary by area, so I want to avoid getting a large amount injected unconditionally. I am curious how those who have received filler consultations described the shape they wanted. Rather than a drastic change, I want my face to look a little more relaxed and three-dimensional. I also want to naturally correct only the slightly sunken part of my forehead, but I would like to know if they consider my overall proportions when consulting on multiple areas together. I am also curious if there is a difference between treating only nasolabial folds separately and treating the front and side cheeks as well. Please let me know if bringing photos to the initial consultation would be helpful. I would like to use any real-life experiences as a reference during the consultation.
