I find the bridges to be rather brilliant, as they're distinctly European without being placeable (until Spijkenisse got feeling[1]).
The least historical governmental buildings in Europe seems like an awful choice by contrast: They're tied to a physical location in western Europe that most of us have little to no connection to. They're boring (which is not a criticism of the buildings, they're functional which is their purpose, but I'd rather not see them on coinage).
For a similar reason, the portraits are also just... fine. Greek, German, Polish-French, Spaniard, Italian, and Austrian. It's much more diverse than the buildings, but the Balkans, Nordics (including Latvia and Estonia), Benelux, and other smaller states remain unrepresented. Of course, changing anyone out would leave another unrepresented (though the obverse and reverse could both be used in harmony, why does the reverse have to be nondescript?).
If we're going for people, one thing I really like about the Swedish bills is that the person on the lowest denomination is specifically chosen to have an icon for children: Currently Astrid Lindgren and previously Selma Lagerlöf made the 20 krona bill distinctly "for the children". The choice of Bertha von Suttner for the highest denomination is one that I agree with -- and also aligned with the Swedish bank notes where the equivalent is held by Dag Hammarskjöld. Both ECB and Riksbanken chose a person best known for their pursuit of peace and unity of humankind.
Still, the beauty of the bridges is that they're European, not French or German.
All that aside, I'd hope for F or J stylistically. There's too much vectorization happening on most of the others. It feels like the others won't stand the test of time. G and C already feels ten years out of date imo.
