I'd go for *.com domains.
I don't want to impose anything.
Maybe we should conduct a user survey?
🤔
You can use this to help you find domains:

Just enter two or three words in English, and it will give you some domain ideas.

Of course, there's no need to overdo it with the number of domains.
Because you'll have to pay for them annually. 🙂

Cheaper to maintain are: .eu, .it, .fr, .de, .es
But the reach of national domains is much smaller.
