I don’t think you realise how difficult it is to get citizenship, especially Poland. The language test is notoriously difficult.
Back to OP, you won’t get hired by any European airline without unlimited European right to live and work, so EU passport. Has happened in the past for highly experienced pilots but those days are long gone and you aren’t highly experienced.
But it’s not all bad as you can work as an instructor or at a smaller company and build experience. You can live quite well instructing full-time in Poland and with a permanent residence permit and lots of hiring you may be able to find something (Covid-19 recovery etc etc)
