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.
I think it might be confusion between inspecting plaintext metadata like SNI vs actually inspecting encrypted contents (e.g. HTTPS content, headers, etc.).
