Casting the net a bit wide here, but if you or anyone wants to highlight some preferred genres I can probably zoom in on suggestions. Some personal favorites in the Funimation catalog include:
-Space Battleship Yamato / Star Blazers 2199 + 2202. Hands down the finest space opera anime done in recent memory, marvelously updating the original with gorgeous visuals and a more diverse ship crew without losing the soul of the original. Without question the first thing I'd recommend to anyone that's enjoyed anything Star Trek, Battlestar Galactica, Babylon 5, etc.
-Fruits Basket (2019). The remake of the classic shoujo is basically everything I was hoping it would be, and the way it blends humor and drama is still second to none. I love it. Season 2 is going to be delayed for an unknown period because of Coronavirus, but that still leaves 14 or 15 dubbed episodes to get into.
-The Heroic Legend of Arslan: Based on the manga by Hiromu Arakawa (Full Metal Alchemist), which was in turn based on the novel series by Yoshiki Tanaka. Revolving around the tale of a seemingly underwhelming Prince who has to take up the fight for his homeland when treachery brings about the defeat and capture of Warrior-King jerk father. The series does a great job showing many sides of the conflict, and it's satisfying to see Arslan going from having just a pair of exceptional aides to an entire network of friends and allies that'd follow him anywhere. Arslan takes inspiration from Persian history and also does a very good job tackling its share of issues: slavery, religious fundamentalism, what makes a good ruler, idealism against realpolitik, and more besides.
-Snow White With the Red Hair: Not to be confused with the fairy tale. A young woman leaves home to avoid the advances of a boorish prince and puts down roots in another kingdom, where she trains to be an herbalist and falls in with a bonafide Prince Charming and the people surrounding him. This one's just a feel-good anime from start to finish, packing a nice love story showing off a surprisingly well balanced and positive relationship. Studio BONES does a typically great job making it look amazing.
