To optimize fonts for your WordPress site, use a limited number of fonts and only include the font styles that are necessary. Consider using variable fonts and the font-display: swap property to improve font loading performance. If possible, use local fonts to avoid making external requests. These optimizations can help reduce the loading time of your site and provide a better user experience for your visitors.

To improve font loading performance, consider preloading only the fonts that are used in above-the-fold content. Preloading unnecessary fonts can increase the Largest Contentful Paint (LCP) metric, which can negatively impact page load times. Using critical fonts is also a recommended practice.
