I don't think we know how small of an effect gravity can have over a large distance. Is there a lower Planck-like limit?

Only in speculations that we have no way to test now or in the foreseeable future. We are many, many orders of magnitude away from being able to probe spacetime on such scales.

From my (complete lack of) understanding, it’s unlikely that spacetime is discrete, so maybe not.
