I don't think any of the national id services I've heard of stores all your data in a centralized place. Usually the national id service only provides identification to the service providers that request it. Each service provider (like, your bank, hospital, pension provider) will store their own data as they've always done, they just use the service to identify you.

There’s data scoping per request:

As part of the flow you’ll be shown the list of data that’s being requested.

In Finland there is centralized database of all medical records. Which makes information transfer simpler. There is ofc risk of untheorized access. But for that reason legal system exists. You get audit trail and then can prosecute or fire those who accessed information unnecessarily.

It is trade-off, but probably lot more accountable than paper records in big hospitals.
