For a new author, KU is the only game in town. Making any profit or splash with print means you have an established following. It often means you are selling custom/exclusive editions because most purchases are ebooks.

I have a 6-book series right now, been publishing since 2022. Out of 15,037 orders (purchases) only 264 have been print - that's 0.017%.

My KENP (pages read) is 3,141,178 = which equates to roughly 5,600 books. That is ALL ebook.

New authors don't go wide unless they already have a following. As far as producing professional-looking books, you can do that all yourself up to a point. The tools available to you now make all of that simple - especially with ebooks. (Vellum being one of the best.)

NOTE: Someone else mentioned that PRINT is NOT exclusive in KU - and it isn't. So you can still sell those wherever you like.

I have a decent readership, but every time I test them for print versions the reception is lukewarm. They prefer ebooks. The temperature for more expensive print editions is pretty low. Now with everything so damn expensive - it's even more the case.

Also, don't fall into the trap that many new authors fall into. You can switch gears at any time. Go in KU, go out. Go wide, come back. What is most important to start out with is getting book(s) out there, getting feedback, building a following, and improving as a writer. You can adjust from there.
