WordPress is a great blogging platform and offers users thousands of templates to design their own blog. It's easy to use and can be a powerful tool when you take full advantage of what it has to offer. However, it's not the best choice for custom web applications or for those with limited technological skills. Plugins can only take you so far, and the constant need for updates and a limited data structure can cost you more in the long run than a fully customized web application.
Additionally, WordPress is known to mess with the sitemap due to its category system and special labeling that creates duplicates. Programmers and hackers love to mess with WordPress to try to break your site and use it for their own purposes, so you may need to hire several WordPress developers over the next two years to fix your site. Themes are chosen from a catalog, which means that your website is likely to look like any other WordPress website, so it's not good if you are a company looking to stand out. In conclusion, WordPress is great for blogging but not ideal for custom web applications or those with limited technological skills.
