Mathematics is made richer with a diverse set of philosophical opinions. Also, but the paradigm that you think might be "golden" for mathematics changes over time, especially in the partly dialectic process of mathematics, which is constantly synthesizing in unknown ways!
Might there be a "Zeitgeist" or spirit of mathematics then? Just a little joke.....
Considering mathematics, and mathematics alone, Platonism might be the most defendable position available for the power it has describing the realism of mathematics. Then, that just defends realism, not how mathematics is actually done in practice.
