I just installed Ubuntu 19.04 with UEFI boot, selecting Finnish as both the language and the keyboard layout. The layout happens to be correct for me after installation, ä and ö are working and only Finnish is listed in Input Methods / layouts.
(My only problem is that the installer does no longer offer Finnish keyboard by default if choosing Finnish language, a regression that I'm trying to find a bug for)
