Wandering son (Hourou Musuko), it's an anime and though a bit rushed to fit the 12 episode mark it was very good. It's about middle-schoolers which really gives it a chances to focus on how they deal with puberty and all that entails. The main character is mtf and the other is ftm. They also have a friend who is gay and the there's a girl who has a crush on the mtf character. Lots of middle school drama, but not the cringey kind since it's still written for an adult audience. The trans characters I found to be extremely relatable.
