Have used Jekyll, Hugo, and Docusaurus to generate static sites, and Wordpress and Ghost for blogs.
A few things to think about:
- Where do you plan to host and how much is the monthly budget?
- How much traffic do you expect to get?
- Will the content be static or updated often (i.e. landing page site vs. blog).
- Will more than one person be updating the site?
- How technical is the person/people updating the site? Are they OK with using terminal and command-lines, or GUI and point and click.
- Will there be 'member-only' features, i.e. things that require users creating an account and logging in?
- Will you need to offer a way for people to get in touch? Like, contact pages, email, etc.
- Will there be a need for public to post and answer questions (i.e. a forum).
- Will you need future support for things like newsletters, shopping carts, etc.
If one-person, technical, static, I'd go with Jekyll and Github pages, or Jekyll/Hugo/Docusaurus on Cloudflare pages. They all have templates. But you need to know how to setup github repos and tools. Cost is $0 to operate, other than annual fee for custom DNS domain name.
If more than one person, non-technical, or dynamic, then hosted Wordpress or Ghost. Budget for DNS name and ~20-50 dollars or euros/month (plus or minus, depending on features and traffic). There are free versions of these, but they slap ads all over them.
You can self-host all these, but it's much easier to have someone else deal with traffic spikes.
If you need community forums or a way for users to communicate with each other, then none of the above.
