It also wouldn’t be bad either – .de is even here in the EU considered a more trustworthy domain.

Personally I have my main stuff all on .de, my short domains on .eu, and then for certain projects purpose-specific domains on .info

Why even support EU users though with all the GDPR overhead? Unless you are a multinational who doesnt care about GDPR overheads, best not to target the EU market isnt it?
