These features "Fonts Preview should be shown the preview/behavior in their own style in the list for selected text" by showing the name of the font. You can not change the preview and size of preview in the Character Panel, in the Type Menu, and in the Control Bar, either you are not able to modify these options in the Preferences in/under the type. Now this feature is not available in Ai CC 2020 24.2.3, which is annoying. I mean, like Illustrator's recent versions 2018 or 2019 maybe, I saw the text which I wrote, means if you click on the artboard with Type Tool selected, there you have "Lorem ipsum" default text, and now you go up to the control to open the characters/fonts or you go from character panel to see the fonts you have installed in your machine, there you should see the fonts with their names with the preview of select text which is "Lorem ipsum".
