The result of the first and last match looks a foregone conclusion and it seems to me that you can make a bet here. As for the remaining two matches, for me personally, the result is not at all obvious and it is rather difficult to guess the outcome.
Upsets occur when everyone think that the outcome is of foregone conclusion. I am talking about the Netherlands vs North Macedonia match. Now a win for North Macedonia may be unimaginable. But I would say that there is a small chance for a draw. And I would say the same about Finland vs Belgium match. Finland already has one upset to their name (against Denmark, although it was aided by the injury to Christian Eriksen). If they could defeat Denmark, then it is very much probable that they could hold Belgium to a draw.
The fact that the result is not predetermined is understandable. But in my opinion, the odds that I have highlighted in bold look attractive (despite the fact that they are low), and the odds in the other pairs look very doubtful, since for me the result of these matches looks random.
The only thing I am almost sure of is that there will be many (more than 2) goals scored in the Ukraine - Austria match.
