Adding Google fonts to 6.3-rc1 and 2023 theme

I just installed a fresh local site for testing the upcoming WP 6.3 and attempting to follow along with the suggested docs. When I get to the Typography section of the styles-overview doc, there is no hint on how to add a new font other than select “Iter”. Google search brings up a confusing list of plugins and old classic theme suggestions, so what is the best practise for adding a locally hosted Google font to the Styles section of WP 6.3?
