i mean im learning how to use wordpress but there are thousands ways to create a wordpress website/e-commerce, im practicing php and i already know javascript, i would like to see a full creation process of a website using wordpress with gutemberg, what to do if I want to hardcode something, security, seo etc etc...

I'm trying to become a wordpress developer, so i will avoid the uses of plugins during the creation of a website

i know that i could find millions of videos about these procesess but which of these videos are the correct or the currently method to create it? for example i choose gutemberg because i know right now gutemberg is the most used, elementor has sometimes performance and positioning issues if you want to do SEO, for me seo is important

thanks in advance
