With the microservice architecture it’s easier to lock things down. You can’t have someone outside of your team just give access to a dataset or similar because excel can’t get a connection directly into your DB. Which is an argument you could rightfully make for monoliths, except in my experience, someone always finds a sneaky way into the data on monoliths, but it’s too hard for them to do so with MicroServices.

If you gave me total control over everything, I’d probably build a couple of monoliths with some shared modules. But every time the data is centralised, it always somehow ends up being a total mess. With MicroServices you’ll still end up with a total mess in parts of the organisation, but at least it’ll be in something like PowerBI or even your datawarehouse and not directly in your master data.

Or to put it differently, for me MicroServices vs monoliths is all most completely an organisational question and not a technical one.
