There isn't a single IME setup experience on Linux. In my experience, Debian is worse than Fedora, Ubuntu, and openSUSE. Fedora is better than Windows 10 when it comes to IMEs: Fedora installs the IMEs by default. Ubuntu, like Windows 10, installs IMEs when you request the addition of an IME-requiring language. OpenSUSE gives you an IME for the language you use at install time if you install openSUSE using an IME-requiring language. I haven't tried Debian 10, but when I installed Debian 9 _in Japanese_ with a _Japanese keyboard layout_ chosen, the installer didn't bother to set up a Japanese IME! Fedora comes with an OK set of Noto CJK fonts by default. Ubuntu comes with a minimal set of Noto CJK fonts by default, but when enabling Chinese, Japanese, or Korean, Ubuntu drops more language-appropriate fonts on the system, like Windows 10.
