The home page is the main point for visitors as well bots for checking Seo. And with new properties like CLS and first content rendering. We can do things to improve.
1. Use low-quality image placeholders (Reduce Layout Shift)
2. Use of critical CSS above the fold if using minification/combining (Reduce Layout Shift and rendering)
3. Lazy loading content
4. Fewer page elements to reduce DOM size (which is actually a nested code line, the more the content, more code, and more lines, and more DOM size causing more memory to be used)
5. move scripts to the footer and use async so to prevent blocking of page loading
6. Use optimized images to load faster than original (use tools like tinypng to compress and see size reduction)
7. Use fewer plugins in the case of WordPress
8. Lazy load advertisements
9. Use no-opener and external relation tags for a link pointing outside resources.
10. Always provide height-width of embedded images (Reduce Layout Shift and Rendering)
11. Use system fonts (let user use fonts of the device rather than downloading google fonts)
12. Use caching of the web page and browser cache

These are all tasks we can do, plus more other things. But it is not necessary and not possible for all to follow these steps, as all sites have different content. Some may have just a landing page, some may have a full magazine layout.
So, some will have a 100 optimization score, some may have 30. So just try to have minimum and optimized content without worrying about all optimizations.
