Are you kidding? Apache is by far the most used web server for dynamic content-driven sites. It's "killer" feature is its robustness, in particular for (shared or otherwise) CGI hosting (and PHP hosting, of course). Outside the web app bubble, CGIs eg. per-request process spawning isn't a performance problem at all when you're using caching, which Apache httpd conveniently provides with mod_cache; mod_cache, unlike eg. Varnish and other dedicated caching solutions, has full RFC7324 caching with re-validation, not just "Expires:".

Apache httpd in many ways is a much more complete web server solution compared to, say, nginx (which I like as well). I'm prefering Apache httpd for the depth of available documentation alone, because everything is developed openly, C source is accessible and not hard to develop with, and because of the breadth of available options (certbot/letsencrypt/acme reference implementation on Apache, WebDAV, clustering etc. etc.).
