(I've never used 2 - Anonymous function statement).
The reason being that I learned React with Class components, and then hated this so moved toward using functions (especially w/ introduction of hooks).
I then moved onto default export, which I found it easy to declare w/o having to worry about how to name the component.
But then, I have a mouse-jerk problem, so sometimes move files around by mistake. With default export, I have to "read" what the component did, to be able to move it back to where it was.
When you name a function, and export it that way, you know what the component is w/o a second thought.
I am a frontend developer best known for developing highly performing web applications using most modern technical solutions which proved to stand the test of time. My best work is in ReactJS, NodeJS.
I think one more reason why export default function approach might not be preferred is when you write propTypes and defaultProps. Because these require the name of the function to assign those types.
I went from
5 - classic component syntax
1 - Function declaration
3 - Arrow function statement
4 - default export function
then back to 3 - Arrow function statement.

So my preference nowadays is the 4th one.
Very good.

That's actually a good reason.
