These are the rules for elections in Sweden; one year until you can vote in local elections, five years for national elections. You should always research this when entering a new country for work, applying for citizenship is usually a very rigid process, and it will depend on the time you send in you application. I do not know if these rules are the same all over EU. About cooperation between countries; At least the gears are turning, even if it is not somethings that is high on the political agenda. The biggest issue is to have a central database that maps one identity in one country to another. We have not even figured out Inter-country Electronic IDs (via EIDAS) yet, there is no way to even do a manual match of identities between countries using eID. That makes it impossible for you to log on and check your pensions if you work in the wrong country.
