In which case you’re back again in PHP land.
In my mind a "more or less static website" will not require a database, it will not require logic server-side, and it will not require the possibility to add-on plugins for extra functionality.
What's beautiful to me about static websites is that the threat vector is now suddenly nothing but the web server, and when you're serving static web pages that's a pretty small threat vector if you've configured it correctly. As soon as you blur the line between "web site" and "web application" and start including things like databases, forms and API:s you're in a completely different territory and I kind of feel like you should choose that because you really, really need it. Not just as a default.
WP hasn't been a good choice for small business owners for a long time - web security is hard, and hardening a WP install is not simple. There's a ton of options out there that do everything WP does without the overhead: squarespace, weebly, wix, shopify, etc.
I'm not disagreeing with you, but "website development" is a very broad category. For example, if you definitely need a website with server-side logic and database connections, yes, that's where PHP will shine. However, if you need a more or less static website for your restaurant or portfolio, is it really as straightforward to say "PHP is for website development, write your website in PHP"?
I want to be very clear that I'm differentiating between use cases here, but for something like a technical documentation website, a status page or something similar that does not require server-side logic and databases, I would much prefer using Hugo or some other type of static site generator, and not because PHP is bad but because we're still talking about "website development" but just not necessarily the kind of website that PHP was made to build.
That being said, there are of course static site generators in PHP as well (and probably every other language out there), but Hugo has a special place in my heart just because of the speed of it.
