I have been working on improving page speed for a website (using Sanity and Recaptcha). There is a difference in speed for Mobile and Desktop. Is it just because PageSpeed uses mobile simulation?

I can notice that PageSpeed shows font issue in Network Dependency and I am using Next.js font with display swap, it should not be raised, right?

Can someone take a look and let me know what I can improve? And will those improvements be really worth it? I have already made changes like removing Vimeo, and lazy loading Recaptcha (it improved the score from 49 to 74).
