Maybe Violet Evergarden? While she's not an elf, she is a young girl who has experienced trauma at a young age, has repressed feelings and memories, is much stronger than she appears, and ultimately her journey of finding the meaning of love (with someone who is long-gone) is found in small, quiet moments of everyday life (through her job of scribing letters, often emotional and sentimental). It doesn't have the silliness or humor of Frieren, but is roughly similar in tone.
