EU OS is a new—still in the idea stage—Fedora-based Linux project designed to provide the EU public sector with secure, sovereign, and eco-friendly computing.
You are supporting a US company (RedHat) while you could support an European one. You also rely on US based server bound to US patent laws (which are much more crappy than EU ones). OpenSuse uses rpm too so you wouldn’t give away much. OpenSuse is also back by the oldest company (German) selling Linux as a product so you’d have great support. As highlighted by others, otherwise, Ubuntu is more widely use than Fedora and Europe based too. By your criteria (support out of the box and troubleshooting articles online) Ubuntu should be the winner.
