Answer 1

TL;DR: No, there's currently no official way to center the title on a toolbar.

I don't think there is an official way to do it, at least not yet. But I know that the Flutter framework supports it and it's pretty straight forward: you simply need to pass centerTitle: true to the appbar constructor, as described in this answer. And there's a good chance that the apps you've mentioned in your question were built with Flutter, since both are from Google.

I think the closest workaround to your expected layout is having the TextView on top of the Toolbar, as shown here:

But it would be really nice if the official Android API could support this the same way flutter does. Maybe you'd like to send a feature request to the Material Components Android Issue Tracker?
