A web fonts API is coming in Gutenberg 12.8 and should land in WordPress 6.0. I have no doubt that we'll start seeing font plugins popping up to take advantage of it, letting users choose from a range of options.

WP 6.0 should introduce global style variations (already in the Gutenberg plugin), which will let themes ship different site design presets. And, these can also use the upcoming fonts API.

So, there's definitely some font-related stuff to look forward to.
