@PierreMo - Start by ditching Google fonts by loading them locally. Understand that Webflow interaction code is loaded everywhere, not just where you are using them. I prefer to use animation alternatives like GSAP since I can control where they are invoked and whether the library is needed.
Ditch the whole logo thing since a simple image is more performant and animations are just a distraction which don’t help the page conversion rate.
Run the site through a analysis on a tool like pagespeed.web.dev or webpagetest.org and follow the recommendations to resolve issues.
