Does it look like I would need a tummy tuck, or would another procedure be better for what I’m trying to correct? (Photos)

I’m a 37-year-old female, 5'3", 129 lbs, with what I believe is normal skin. I’m 9 years postpartum from my third C-section. I’ve been consistently exercising and strength training, with dedicated diastasis/core rehabilitation for the past several months. After an evaluation by my primary doctor, I was told I have only about a 1 to 2 finger-width gap. I’m mainly looking to improve my lower abdominal projection and the area around my C-section scar, and I’m wondering whether a tummy tuck or another procedure would be best for me.
