Joomla

I started using Joomla after having my sites on WordPress for years. Its similar to WP in many ways but enough different that I prefer Joomla. I've found good help and a good community with Joomla. Don't try to learn by using example sites as most of the books do. That makes it really confusing. Just start using the software, adding some posts and read about how the backend works. Core Joomla has everything you need to get started so don't start looking at plugins thinking you will need those right away. Good luck!

Great for larger websites that require more security than WordPress

This used to be the go-to CMS a few years ago, and it is very well supplied with themes and plugins and stuff. But nowadays there are better CMS out there that are more intuitive to use and just do a plain better job overall. It does a lot, but nothing really good. Also not very easy to create templates for. I suggest trying out Contao instead.

easy, simple and easy to customize but for a larger webiste and with that, more content, it gets really difficult to maintain. Not what I wanted.

I think the problem with this open source cms is that it is easy to create your website and play around as pleased but when your website gets bigger and reaches a larger audience and you start to actually make money from it, it becomes quite hard to keep up with the updates and changes.

I do think is better than wordpress but I still don't think this is meant to work with large websites. The amount of themes and plugins are good but it's not as easy as you would expect. Maintaining a large site could be quite complex.

so I tried this one before and was pleased with the amount of plugins you can easily use but in long term, it didn't work for me. Maintaining it is quite complex and specially if you have somebody else doing the job after.
