It's worth considering why you are choosing a European stack.
Is it to support local/European companies - Great. Is it because you don't want to be at risk of the US and the CLOUD Act - Not so great. Any company that has servers in the US (which Hetzner and basically all CDNs do) are still vulnerable to the CLOUD Act and that includes servers in Europe.
