If you're specifically asking for plugins then you're in luck because the XIVlauncher is borderline required for Linux at the moment unless you use Steam.
Get the Flatpak version, its even included in most package managers without even needing to download external shit, and everything will run just like it did on Windows with maybe a couple of quirks like ScrollLock to hide your UI not behaving the way you're used to.
