Welcome to the forums! The first songs that came to mind were the
ocarina melodies from Ocarina of Time, most of which are quite simple. If you’re looking to try something with two hands, the on-site arrangement of
Zelda’s Lullaby isn’t too bad either, though it may be little tricky if it’s your first time trying something with two hands (nothing wrong with that though, it would be something to work on!).
Another thing you could do is look through some of the arrangements on-site to find some songs with simple and memorable melodies and just work on playing the melody (which is usually the top line of notes) for now. I did this a lot when I was a beginner and it’s a good way to get more familiar with both the piano and reading sheet music.
Good luck with your learning, I hope you enjoy your time playing music!
