Depend on what you’re interested in watching
Buddy complex: This feels like a classic mecha series despite being somewhat recent. The only thing that is not classic mecha is its runtime at one cour and a few ova to wrap things up.
Witchblade: Anime from the mid 2000s based on a western comic book. It feature a really strong and heartwarming mother/daughter dynamic with a bittersweet ending
Wandering son: My real recommendation. It is a deep dive into the experiential feeling of being trans. Fair bit of warning, it might be a hard watch for some for how close the event depicted hit home, make sure you are in the right state of mind to watch it.
