Thanks for the further tips!
A few more comments:
Website tools should be designed for the large mass of users. If someone wants to work with HUGO without CMS and without WYSIWYG editor, this is not a problem, he can do it. I myself did my 3 hour tests in this way.
I spent another 3 hours to read part of the documentation and also to look at a few CMS and WYSIWYG editors, just the documentation.
6 hours of effort and I don’t have a handy HUGO development environment yet. To get one, I now have to install and test different CMS and also different WYSIWYG editors. Another 10-20 hours of effort? To manage a single website? It’s about the relations. If I had done the 6 hours of effort for a customer, he would already have to pay an bill of 1500 US dolar! Yes, this are the prices on the market.
So it’s not a question of whether someone is willing to learn something, but whether they are able to bear the costs of it. Most people have to work hard for 8-10 hours every day to survive, a boss of a small company even longer. There is not much time left to evaluate website tools, so you give someone the order for it and pay for it.
For this reason, the three packages proposed above would be very helpful. With the first one, HUGO base, you could already know in 2-3 hours whether a HUGO solution is the right one for the individual situation. With other static website builders, this can be determined in this short time. So my suggestion is to be understood as a well-intentioned tip to make HUGO more attractive for beginners.
In my search, I came across another possibility that might be useful in my case. It is localWP, a tool with which you can develop WP locally and then host it as a static website. I will take a closer look at it and at best keep my exported WP website alive with it. This gives me more time to continue testing with HUGO, i.e. CMS and WYSIWYG editor. Theme builder is also important.
HUGO is certainly a very powerful tool. But even such a tool can be used for very simple projects, if there are special packages for this. Surely you could also make an online platform with HUGO, as is the case with other CMS, for example WIX.
It took a good team, a good concept and a few weeks or months. Then HUGO would be interesting for beginners and small companies as well as for advanced website developers. This is also the case with WP, DRUPAL or TYPO3.
Well, but the HUGO community has to decide for itself whether it wants to “sell” HUGO, even if it is free. Personally, I think that I will continue to develop with HUGO, rebuild my old WP website and also start any new projects with HUGO. It looks good and I don’t have to earn any more money with it, because I have made Informatics my hobby for a few years now. At some point you get tired, after 15 years of project management and many endless discussions. There are other interesting things to do in life at the age of 53 
have a good weekend!
