Ublue also has Asus-specific variants which I assume probably has some compatibility fixes added in that would have to be installed manually in most other distros.
Since you use VS Code I’d strongly recommend the developer variants of ublue, which are only available for Aurora and Bluefin, as it gives you a preinstalled VS Code which will be a better experience than trying to install it after the fact. (if you go to the download page for them, answer “yes” to “are you a developer?”)
For minimum learning curve, use Aurora over Bluefin as the UI is more familiar. Also, make sure you pick the Nvidia option for the GPU question.
Because the Linux Foundation says so. I would guess it’s because most of the relevant tech started as cloud products or services and got generalised, such as Kubernetes (the big one in CNCF).
The naming wasn’t up to Bazzite or uBlue to decide, that’s for sure, and the term “cloud native” has won the mindshare of developers.
The irony hits hard when you’re logging into an on-prem Kubernetes cluster in your company’s wholly owned data centre. At that point, “cloud” isn’t even someone else’s computer (as the FSF would say).
