David Weber’s Honorverse and Mother of Demons by Eric Flint both come to mind. There is also the Little Fuzzy series by H. Beam Piper.
Edit: Also, The Legacy of Heorot by Larry Niven and Jerry Pournelle.
Honorable mention also to Dragons Egg by Robert L. Forward (humans start out more advanced in the beginning but get surpassed) and the Uplift Storm trilogy omnibus (or books 4-6) from David Brin (humans aren’t the most advanced in the entire universe but are in the planet that the stories take place on).
Any sci-fi with aliens where humans are not the less advanced race?
What the title says, I’m tired of the trope where humans are the least advanced in the universe....
