Regarding the Scandinavian bases, you will not get one of them when you come in as a DEC EVER!!!! There are countless first officers that have not gone for their command in order not to be moved from their home base and they will be first in line, strictly according to the MSL!
If for any reason in the future, they need additional captains in the Scandinavian bases and cannot crew those positions with the people already there and ready to be upgraded, they MAY, and only if the NPU agrees, take on additional captains from the Euro bases, again strictly according to MSL, which at the moment would mean there might be a few hundred people ahead of you, wanting one of those spots, so again, do your time and eventually you MAY get there!
If you now wanted to come in and bid for any of those bases as a captain, you can of course do so, but you're unlikely to ever go there as a captain, if you agree to fly as an F/O, you might stand a chance.
