Did as you suggested with the links and used the Elementor list widget. Adapted the hover color to red. In the preview it appears like this but on the page it seems to be overwritten by something. Please also see screenshot.
On the button color, also no news. My question was where to change the border color. In your screenshot I can also just see the border type (which is default) in my case. However that doesn’t explain where to change to border color from currently green to red. Or maybe I confused something and you pointed to another setting?
