Most of them look better than they did. The combobox is still a mess though. It's always been one of my least favorite controls, mostly because of the UI. Now, the flyout menu is detached from the base control, making it worse. It would be good for the design team here to take a look at how popular web frameworks have implemented dropdowns/combos, and take some inspiration. Things like the button morphing into the overall list, and losing the dividing line between the bottom of the entry field and the list of options. The focus highlighting is excessive in my opinion and will lead more designers to disable it - not a great step for accessibility. Maybe put the high contrast version behind a browser option/high contrast mode for the system, so it's a little quieter. In any case, happy to see progress on modernizing native form elements. But I hope these don't make it upstream without some significant UI polish.
