Is there any way to trigger the night mode (vibrant red variant) for Standby when using the iOS 17 simulator or is that only testable on actual hardware devices?

Apple's Weather app StandBy widget uses a font for the temperature that I can't seem to find how to access. As far as I can tell, it is some variant of SF Pro, but it isn't the default and it isn't rounded. To my eye the slightly rounded corners look significantly better in places where the text is really large. Does anyone have any idea how to specify the mystery font as seen in the included image?

There are some Apple widgets (like the Weather Stand-by widget) that use some extra large versions of numbers. In those cases, they appear to be using some modified version of the number glyphs that is much more pleasing to look at. The default corners are very sharp, but rounded makes the letters overall bubbly. With this mystery difference, the overall letters are scare but the corners have a radius. I have been completely unable to replicate this.. Can anyone please point me to how these alternate symbols can be used? It is driving me crazy that this exists but I can't access them.

The problem that I am trying to solve is a scenario where I have a vertical stack (specifically in a widget) and the subviews are of various heights. I have more views to show than can possibly fit, but determining exactly how many can fit is hard to do. I love to be able to give the view more subviews than it can show and let it show what fits and hide what doesn't fit. Ideally, I would love to see something like List supported in widgets where, instead of a scroll view, it was a limited space view and just cut off what couldn't be fit in the available space. Is there any way to do this with the tools we already have?
