Interested in improving my smile - can’t decide between dental bonding or veneers, which option would be best for me? (Photos)

I had braces when I was younger to correct misalignments and gaps between my teeth. I’ve also had composite finding done to my central incisor after chopping it when I was around 8 years old. I am now 27 and that filling has lasted for almost 20 years! However, I’m now interested in fixing the discoloration it has in addition to adding more length and possibly width to the rest of my front teeth. Mostly cosmetic concerns. I’m wondering if veneers or tooth bonding would be the best option for. I’m more inclined towards dental bonding because it’s more affordable and less invasive. What should I do? Am I a good candidate for dental bonding as well?
