Which font setting is best for Core Web vitals?

I’d go for the 2nd one, but the best thing is to try and compare results really ??

Thanks. Do you suggest that I clear the cache, or something else, before I retest the core web vitals?

yes, you will have to clear the page cache for the page your testing (else the change will not be visible) and request it a first time from an anonymous/ private window to ensure it is in cache.

I have it on my to-do list to look into more at some point. Don’t know how well it works, but I’m very curious to see it in practice. It’s basically loading fonts late but also finding a built-in font that closely mimics what the text will look like with the final font loaded.

I will look into that. Thank you both.
