Radiobuttons/Checkboxes in windows11 style do not follow WinUI3 style

I compared the checkboxes/radiobuttons style from windows11 style with the 'official' Figma/MS style examples (Figma WinUI kit and WinUI 3 Gallery) and found some differences which I'm not sure if they are indented or were simply overseen:
Differences in the WinUI 3 style

• a checked button has no border
• when the mouse is pressed on a radiobutton, the inner circle has the same size as without mouse focus
• the accent color is lighter when hovered
• the checkmark is black instead white
• the intermediate checkmark is shorter
• the buttons are greater (18x18)

maybe other misc stuff I forgot to mention.

I've provided a wip patch to fix some of these issues but the main question remains - do I look at the correct template? Or do you use some customized winui3 style which I'm not aware of?
