But 'system-ui' is... well... intended for UI usage. It may not be so well suited for page content. If you're creating UI elements on your web page (though why aren't you using the browser's built-in form control elements?), then 'system-ui' is probably appropriate. But if you're publishing textual content (rather than UI), 'sans-serif' or 'serif' may be a better choice. Most browsers even let users configure their preferred fonts for these generic names, if they don't like the defaults.
