Law / Any advantage to citizenship of Poland if already have EU residency? [20]

I am an American citizen and my husband is a citizen of Ireland. My father was born in a part of Poland that is now Belarus. He fought in the underground resistance and was awarded a Virtuti Militari medal before emigrating to America shortly after WWII. My mother was born in Ukraine.

My husband and I have not been able to have children and are considering adoption. I would like to adopt an older child or sibling group from Poland since we have Polish speakers and Polish customs in our family and I would like to continue those traditions.

Since I have lived in Ireland and the UK with my husband before we settled in the USA, I have residency permission for the EU. I have often thought about applying for Polish citizenship due to my father's side of the family all being Polish, but as I already have permission to live or work in Poland due to my husband's citizenship I'm not sure if there's any point. Would it help with adoption in any way? We have no immediate plans to move back to Europe.
