You have a great camera that is capable of integrating fully with Nikon's most capable speedlights. I second the recommendation for a SB-800. If you want something small, look for a used SB-400. It can be controlled by the camera's menu system. Just be aware that it sits very low, and can vignette with some large lenses.
Another vote for the sb-800. That is what I use with my d500.
