Learning to play by ear and learning to play from a score are both useful and reinforce each other.
In addition, I would encourage learning to use music notation software like Musescore. These days I transcribe a lot of pieces because I have preferences about how they’re laid out on the page. (I prefer lead sheets and dislike turning pages.) Also, for some pieces I want to play, the sheet music isn’t available. Listening to a recording to figure out how it works can take a while, so why not write it down? You don’t want to forget and have to do it again.
Having a three ring binder of music laid out how you like it is very nice. It makes it considerably easier to go back to a piece if you haven’t played it in a while. You can also change it whenever you want and print it out again, making it more your own arrangement.
