If you're worried about "total bank surveillance" (which seems to be most people in this thread), don't. Every single bank you have an account with already has to keep track of know-your-customer information. It's not like the fact that there's a centralized digital currency will give the government more control over you than not. The government can simply tell the banks to hold your assets, put you on a list that prevents payments providers to service you, etc.

The digital currency won't make any of that worse.

The good thing about digital currencies is that'll actually take power away from commercial banks. Right now you need to go through someone like Barclays, HSBC, etc, to get your money. CBDC actually lets you keep your balance directly with the government ledger and avoid relying on banks for everything. This is a good thing.

Beware that commercial banks are obviously opposed to this and will be very vocal about it.
