I love using WP for my blog and I've a self-hosted version. In your question "new websites for beginner" indicates that the user is a beginner and wants to build websites. If websites have simple and static content that don't involve any serious stuff (e.g. e-commerce) then WP is probably ok. But for serious work i won't use it.

I’d almost say the opposite.

For a simple website it’s overkill.

For a serious website there’s not much else that has the extensibility. Woocommerce is nearly unrivaled. There isn’t another ecosystem like it. I would think this community would lean towards the open source leaning products to the shopifys.

What would be your choice for serious work then
