I’m going to say Debian or RHEL. Both are extremely well supported by software and very stable, but you’d get administration benefits with RHEL that you would be missing with Debian. Since these computers are public-facing I’m going to STRONGLY recommend against smaller distros like Zorin or Manjaro.

Debian and RHEL are proven to be stable for professional work. Debian is especially notable for being on the space station. RHEL is used by basically every company that uses Linux in an enterprise environment.

Opensuse tumbleweed. Its rolling release and gets lots of packages and is pretty stable NASA uses opensuse for there computers. I run tumbleweed on my laptop and btfs is really good and i havent had any issues minus one time i forced powered off while it was updating and it broke zypper. Plus side tho is the live boot can "upgrade an install and fix things like broken package managment. Aswell as opensuse is based off of rhel so package support is really good

You word structure is a little odd but I think I can figure out what you are trying to ask.

If you looking for desktops I would focus on stability and reliability. For the desktop you could use something premade like Linux mint or you could roll your own with custom Xfce4 configs.

The real question is how you are going to manage this. I assume you have some sort of active directory environment but your group policy will not work on Linux. I would setup Ansible so that you can manage all the desktops in one place. You can create a Ansible playbook that domain joins the machines and then sets up the system.

OpenSUSE newcomer here, from decades of Debian and Debian derived systems.

I vote Debian with Xfce4 for the base system with Nix or Guix to let the kids freely install and play with software as required without requiring root. Stable release should be good. Testing release if time and resources to keep up with the updates are at hand.

Along with teaching the kids computers and software, please also consider teaching them how the Debian packagers, maintainers, developers, testers, admins, etc work and might never meet others in the project whilst releasing a great system every couple of years.

Kubuntu and Fedora KDE are probably the safest options. Linux Mint (Cinnamon) should also work. I’d go with KDE, as it looks and feels similar to Windows, which will make it easier to learn for new users. Cinnamon is another great choice for new users. The file system doesn’t really matter, ext4 should be fine.

Ubuntu LTS with gnome or linux mint. Most available documentation, easy to use, hackable if needed. Make sure it doesn’t crash on the kids!

if the lab users aren’t adults; i would go with an immutable distro

Just wanted to say your English is wonderful.

It does not matter at all. All are linux. All work. It depends on what you do with it. There is no completely wrong decision.

Look at what schools in your area are using. Pick that.

If I had to make a recommendation outside that one: RHEL. You’re literally their target audience.

Debian, honestly.

Check zorin os, it’s Ubuntu LTS with a familiar look, and wine well integrated. Veyon sw then is probably good for pc control

I’d use fedora atomic, specifically ublue, because you can fully control what the os is.

1. It installs updates while it runs and at the next boot it boots into the updated image. If an update fails, it boots into the old image.
2. Most people don’t know WM. Use a DE. It doesn’t matter which one you use KDE or GNOME. Both are stable and solid. It’s up to you. Maybe choose it based on the apps you use.
3. Other questions are redundant.
4. https://universal-blue.org/ https://github.com/ublue-os if you’re interested, use https://blue-build.org/ and your own OS is ready to go within minutes.

I would probably do debian 12 with kde, xorg, ext4. Not familiar with debian edu though.
