Hi
I guess when working with Google Fonts you can just drop the &display=swap that comes on the end of the served URL. The font will behavior as a font-display: block;
ex. <link href="https://fonts.googleapis.com/css2?family=Bebas+Neue" rel="stylesheet" />
For me, it worked pretty fine, without real notice of the delay, and giving - in my opinion - an experience way better than with FOUT.
