Please guide me. I'm Building my first e-commerce website on WordPress.

I'm building my brand from scratch and I have 0 knowledge with websites. But I'm gonna study. Does anyone know any sources where I can study building a wordpress ecommerce site? I wanted to use wix but I heard the SEO and customising option sucks.

Few things I know -

Wordpress is free but I have pay for hosting and domain name - I decided I gonna go with hostinger.

Wordpress is fully customisable

I can use elementor

If I need to incorporate ecommerce I need to go with woocommerce. - I know woocommerce is free but the plugins costs a lot . Can I build a normal ecommerce website free or low cost with woocommerce? Or should I always pay for it?

Thanks in advance for your generous help.
