I migrated my blogs from self-hosted WordPress to Hugo powered static pages deployed with Netlify. Small post on the what, why, how and some tips to migrate https://sathyasays.com/2020/08/28/migrating-moving-your-wordpress-blog-to-hugo/ (I migrated about a year back.. only wrote it now)

Why didn't use some caching extension for wordpress like w3tc or wp super cache? You get the flexibility of wordpress and static serving too Plus, wordpress supports markdown now

I'm ok with not having flexibility. Just don't want to run any servers.
