Regarding European languages one can never go wrong with the Assimil series so I’d check that first (it’s available on annas-archive as a zip archive with the audio files included). You can make a solid base with just Assimil, but you can also include anki decks or grammar drills corresponding to your current level to progress at a brisk pace.
