Yes, the EU allows member states to punch above their weight when negotiating treaties with foreign nations and the harmonized single market is economically benefitial for many people and Industries. Especially after Brexit people start to realize that. (Thank you UK?) But there isn't a EU national identity to speak of. Mostly no one would say "I'm a citizen of the EU" but "I'm a citizen of France/Germany/Poland which is a member of the EU". The "in group" vs "out group" distinction runs along national borders when it comes to language, laws, news, government and culture. At best there are "even-more-out groups" when it comes to EU-foreign topics such as economic treaties and refugees.
