No matter what foreign currency you are, you can withdraw US dollars at home, but a card with US dollar currency will save some money when you withdraw US dollars.

Generally, the handling fee for withdrawing cash from cards at home and abroad is 3%. However, if you are a euro card, in fact, at the time of liquidation, the issuing bank bought dollars with the euros in your card. If you change it again, it will cost a little more, but there seems to be no unified statement on how much it is, and no one can tell clearly. Anyway, it is less than 1%.
