I wish you could create a better and simpler way to type on path, especially on ellipses / circles. It's SUPER difficult when you have to work with multiple lines in a circle, like we used to on a CD for example.

My pitch:
What if we could treat typing on path like a text box? So you draw the ellipse / shape from the Type on Path menu, and the text automatically gets treated as if Typing on a line / shape?
And when you press Return, it behaves like it would in a paragraph (text going to the next inner line), but within the shape. And you can even adjust the line spacing. Take the ease of the radial repeat tool in Illustrator, and add it to this tool.

It's type in a textbox, but applied to Type on Path. See screenshots attached.
And selecting the object: Only the text is selectable, and the lines of the ellipse is "invisible." You have to click on the visible text of that shape to edit / move it.

And when you double-click on that text, it still behaves like Type on Text, until you "expand" it... But you won't have to continuously lock and unlock loads of circle paths anymore. What if you only have to select the text, and not the shape? Wouldn't that be simpler and more efficient?
This was an okay solution for 20 years, but it's time for an improved way, Adobe.

This whole idea eliminates the annoying task of having only a single line of text on a path, and accidentally selecting all the other circles to get to the desired text.
This way would be so much simpler.
