Differences in templates - legacy vs new arch

Problem Description

There are some differences between a newly spun up Legacy app vs New Arch app. See the table below:

	Legacy	New Arch
Default template
Removed some JSX
<Button /> nested inside <Text />

Steps To Reproduce

1. Init a new project on 0.79.0
2. Run the template
3. Delete all <Section /> elements but one
4. Add a <Button /> inside <Section />
5. Repeat with --template cpp-app and observe the differences

Expected Results

I'm unsure of what to expect, since I know there are different philosophies behind the UI in Legacy vs New Arch if I'm not mistaken? UWP vs WinUI?

But I'm not sure if you wanted it to look the same, such as the dark title bar in new arch. It also seems odd that the same exact code in terms of the starter app template from RN core behaves differently (the style of a shorter ScrollView and then the nested Button issue), so maybe it's a New Arch issue.
