Bitcoin can not do the job, that is for sure.
It depends on what they want to be "the job". And I guess that even inside their "board" different entities have different goals there.
They are not really looking at a decentralised community nor anything of the like, but rather to an Euro pegged coin that is controlled centrally. This is not really about cryptocurrencies but rather a way to make money ownership easier yet at the same time more controlled by a central bank.
It can be the price of the printed money they want to get rid of, it can be VISA/MC fees they want to get rid of, or, obviously bigger amount of tracking and control.
As I said, there are probably multiple goals there.
Of course, imho Bitcoin would be the best, but I won't hold my breath for such a decision.
I do see the possibilities of avoiding intermediaries and perhaps the ability to bank the unbanked.
Most of unbanked are so because of the lack of internet or because they cannot use technology (usually old people and/or from remote areas).
And of course, it's also those don't trust anything else than "hard money".
So the CBDCs won't do wonders. They can help, but won't do wonders.
