Trainline works well enough including refunds, seat selection, etc.

It can't book the Eurostar as part of a larger trip and there might be similar limitations.

Wow thanks for the hint, I did not know trainline it even shows the connections I’m searching for where trainitalia, sbb and DB failed :)

Of course - they add their own fees, though I guess there's nothing wrong with using them to find a route.
