Let me make it clear to you then.
Why use Git at all then?
For it's VCS features.
I thought the one reason why everyone wants to use Git these days are the forges.
You thought wrong. Git is not wanted exclusively for the forges, but also for it's VCS capabilities.
I'd do it like this:
borg backup
(optional) borgmatic for easier use, but a diy shell script might suffice
(optional) https://github.com/Ravinou/borgwarehouse for easier gui based "serverside" setup on each location
(if you have no way to reach the servers from the internet yet) set up dyndns for each location so you can reach them by domain
might need to setup portforwarding rules in the router of each location
distributed, asynchronous collaboration and versioning.
Or do you wanna send zipped up sourcefiles "project_dev_0.9.6.2_developername_featureID.zip" per email to a dozen colleagues who then have to manually merge it into their current WIP?
You can do that with caddy as well.
Ban data collection agencies, cause they stalk/harass all users.
I sent your comment (with the licence) to all AI companies, that I know of and they will use it for training data.
Just to illustrate how wrong you are. Might set up a bot later.
If anybody needs a Linux IT guy with 15 years of experience, I'll do it very cheap cause I actually enjoy doing it.
BallisticNG has the option to do multiplayer in either split screen or on a seperate monitor.

X2 had some singleplayer multi monitor features, buf the later games X3, XR and X4 did not...
tldr:
Just becaused you aked so nicely in your post title, let me answer it for you (/s):
It's a proof of concept distro meant for the public sector of the EU but is based on a US corpo distro, so nobody cares. Stop doing pushy marketing for it. It is not funded by the EU and is not official.
We have plenty of properly EU based Linux distros for the public sector in the EU. tbh this is an exaggeration there are 2-3 and they are mostly not general purpose, but they or something like openSUSE would be a much better starting point.
Personally:
I am used to git. When I don't need the webUI, I would stick with git because it is already familiar to me.
