You have similarity measures like mutual information score and generally comparing correlations and distributions.

You can also A/B test for specific use cases, for example train a model on the real and the synthetic data and compare relevant metrics.

You can see some of these illustrated on eg: https://hazy.com/blog/2020/03/23/synthetic-scooter-journeys

There's also some really interesting research from last year on local dimensionality of a manifold that I really really want to try out.
