You also kind of have to count Norway as part of the larger Dano-Norwegian colonization effort with a sprinkle of the Swedish one.
- Kalmar Union (1397 - 1523)
- Dano-Norwegian Realm (1524-1814)
- United Kingdoms of Sweden and Norway (1814 - 1905)
- Independent Norway (1905 - )
Taking over other places around you and politically dominating it is as old as history.
You can't use colonialism as an explanation for anything because in the whole world there were wars and people taking over their neighbors.
Its a matter of linguistics and historiography when we use the term 'colony'.
I believe it's important to acknowledge a distinction between, as you say, politically dominating a region with an intention of expanding the home country and depleting a region of its wealth, exporting it away while imposing an administration with no willingness to co-operate with local population other than for the purposes of wealth extraction.
And its also a limited history of colonialism to claim its only wealth extraction above and beyond what other empires would do.

If anything Europeans because of their limited population had more intensive to do so.
The British take over of much of India was literally a vastly majority Indian affair. The war was fought by Indian troops, supplied by Indian merchants and farmers, it was financed by taking loans from Indian bankers. The amount of British people involved were almost vanishingly small given the size of India.
Did Indians have more control over involvement over India then Greeks did over Greece in the Ottoman empire?
I don't think you can make any generalization that European invasions of other countries were uniquely destructive or extractive compared to world history. There are certainty cases like Kind Leopold's regime in Congo but we can't reduce 600 years of European history to that.
The Swedish in the Thirty years war didn't intend to settle or claim the lands they were fighting in - they just fought against a religious enemy and for power/influence/French money. ( Pomerania is somewhat of an exception).
