As the website I was optimizing was selfhosted, also selfhosting the font had a noticeable effect on the page load time. See https://github.com/SmilyOrg/photofield/commit/12352667c01624...
I'm not sure what you mean with the rest of the comment though, it's a very small change and it gets cached by the browser like other static assets, so I'm not sure what is the overkill here.

Google Fonts has an open issue that is three years old here, with no response from Google:
> Also, please note that Google LLC is certified under both the EU-U.S. and Swiss-U.S. Privacy Shield frameworks and our certifications can be viewed on the Privacy Shield list.
It’s very important to be aware that the Privacy Shield was declared invalid by the European Court of Justice in 2020, so that note from April 17, 2018 is worthless.
