"Scythe" is very good YA Trilogy, "Project Hail Mary" very good for science based sci-fi, and "Way of Kings" is very good if you like strong worldbuilding and large scale fantasy
I only read books during elementary school, but one that I liked the most and that stayed in my mind was:
The Brothers Lionheart
its kids book, but I was so fascinated of the way they approach topics like death and afterlife for a kids book.
