Realistically, most people don't have the expertise of setting up HTTPS enabled web hosting on nginx (maybe Caddy will be easier.) There is just so much prerequisite knowledge for a non technical person to know. What they do instead is either

- Pay for a shared hosting plan on one of the big players like Dreamhost, Bluehost, Hostinger.

- Install wordpress in one click

- Do everything in Wordpress.

- Pray that no one ever hacks their Wordpress installation

Or

- Pay for an agency

- Have an IT professional — like you and me — make the website, and put a link in the website footer saying "website designed by XYZ Inc."
