How to properly delimit data from representation in UNITY?

Question

OOP

For example, there is a Button on the menu with text. The question is how to localize the text on it.
My solution is to create a component and hang it on a Text with a resource connection (where there will be logic depending on the language what to return) from Resources.GetSttring("BtnName",);

And now such a situation, when creating a project, let's say a menu, works with a ton of text, and in the editor itself, as a rule, we write the text, otherwise you will get confused. That is it turns out at me the text 2 times will be appropriated? First, the value from the editor, and then also overwriting it in the localization.

And is there a way to execute scripts in the editor itself before pressing the run button, that is, I connected the component to the object, and it immediately executed, added text. Maybe through attributes?
