CWV and WPBakery Page Builder

Wondering if you can give me advise on something. I am using WPBakery page builder and wanted to speed things up. Is it better to reduce the number of rows and sections on a page or keep everything in as a few as possible? For instance, I have multiple section headings and separate text components. Should I keep everything within say a couple of text blocks and style the headings and other features using my own H tags and inline CSS? I also have some nested rows and sections, should I reduce these as well?

Getting rid of the items/sections are not needed would be a way to speed-up the things as well as using third party software would help, too, otherwise, it doesn’t really matter if you have several headings/blocks or one.
