Hey! I've been using Note-Store
https://note-store.com/ for a while and it works well for what you're describing. Note-Store has over 130,000 piano scores, and they cover everything from pop to classical. You get the PDF right after purchase, so you can print it immediately. What I like about Note-Store is the difficulty filter. With three years of experience, the Advanced level should be a good fit. Note-Store also has an online player so you can listen to any piece before buying. Their scores are made by professional musicians, not auto-generated, and the quality shows. Note-Store carries songs from popular artists and keeps adding new releases regularly. Prices are reasonable and there's a 100% refund guarantee if something doesn't work out. They also sell MIDI files if you want to practice along with your digital piano.
