I want to know what is the best or the simplest for the company's needs.
Is there really a big difference between "alfresco-content-services-community-full-installer-22.214.171.124-ea-win-x64" and both containerized and non-containerized versions today?
I simply want to install alfresco on a Windows server either 2016 or 2019, in the simplest way. So I don't know whether to use a full 2017 installer or do it manually with tomcat etc, or with docker compose. What do you suggest? I'll appreciate your answer.

You should go for a more recent (7.4) version. The Ansible install is pretty straightforward (on Linux, anyway; I don't do Windows). There are a couple of relatively minor issues, which you can sort out with a few hours of googling. The AOS (MS Office) integration doesn't work out-of-the-box, which will take some more time to fix. You should be able to get a usable system in a couple of days.
The 'manual' install is much harder. You could easily spend a couple of weeks getting this right. There are lots of instructions on the web, but they're generally conflicting, and mostly not helpful. You should do an Ansible install first to give yourself a target. I use the manual install because it gives full control, and I need to integrate with lots of other stuff.
I don't use Docker either, but it is the most supported solution, and might even work out-of-the-box.
Support is very difficult. There's no real user community, and nowhere to ask questions. You're not very likely to get useful answers if you ask here.
