Hi Jay,
I think your Inductor/BST/Diode placement looks fine, and you have a nice wide GND plane on top.
However, your input capacitors are kind of far away from your regulator, and the input capacitors on a buck converter are the biggest culprits for EMI in my experience. Please shuffle some components around so you can bring them closer.
Another couple of PCB layers would also help, or external shielding, but these will of course increase production cost.
There is a trace that’s being routed under the regulator, is it possible to keep the GND layer underneath unbroken?
