I’m making a 1000km x 1000km terrain and am having trouble creating wind-blown sand dunes. All I have so far is a Voronoi Noise, then Blurred. It looks more like hills than dunes. Trying to make something like the ref image.

You may experiment with Perlin in this project file:

I do not know yet how to do sandy-effect with new erosion device, but i guess it will also improve this Perlin result:
One quick tip is to take what you already have (Voronoi into Blur) and just add another 2 quick nodes after it to get something closer to dune-like:
Grab a Select Aspect device and an Expander, feed the Blur output into both devices, set the Expander to Shrink (Min), and then feed the Select Aspect output into the Expander as a mask. It won’t be perfect, but it’ll get you the sharper slope on one side of the hill that you see in dunes due to how they’re formed.
