Borel sets with Fourier dimension at least 2 have distance sets of full Hausdorff dimension in any ambient dimension d, and sets with Fourier spectrum at least d/4 + 1 at theta = 1/2 also achieve this even when their Fourier dimension is zero provided d is at least 4.

On Fourier decay and the distance set problem
Borel sets with Fourier dimension at least 2 have distance sets of full Hausdorff dimension in any ambient dimension d, and sets with Fourier spectrum at least d/4 + 1 at theta = 1/2 also achieve this even when their Fourier dimension is zero provided d is at least 4.
