Fate Universe
Anime
Welcome to the Fate Universe, an introduction from the main story line and every spinoff you can imagine.
It's recommended to watch the main storyline first, then branch out to the spinoffs.
The stack is made as an easy watch order for beginners. Fate/Zero is a good introduction to the Holy Grail War, it takes it's time, it has incredible fights, character development and a brilliant ending. It spoils some details about the Fate/Stay Night characters, but not massive enough that you can't enjoy the routes of F/SN. Then you can continue with Fate/stay night: Unlimited Blade Works, which adapts the second route of the Visual Novel which is just as well made as F/Z. Fate/Stay Night: Heaven's Feel Trilogy will end the main storyline, adapting the 3rd route of the Visual Novel, which is pretty different from UBW, but is at least as enjoyable, being praised as some of the best anime movies in the last years. There is also the original anime series Fate/Stay Night from 2006, that adapts the Fate Route (1st Route of the VN), but it isn't a good adaptation, it brought some original content and overall it's much weaker in quality than the adaptations from ufotable (F/Z, F/SN UBW, F/SN HF). I don't recommend it, especially for beginners.
For the people that want to experience Fate Series at its best story wise, they can read from the Visual Novel Fate/Stay Night the Fate Route, which is about 15-20h and introduces you into the Fate Series with more detail, it has some extra content and bad endings. Then continue with the anime serie F/SN UBW, the movie trilogy F/SN HF and end with F/Z. For a Visual Novel reader, this is the original way to experience the storyline. Knowing the ending of F/Z can bring extra weight to the character's actions and their fates, being a Greek tragedy. You can also read the rest of the F/SN Visual Novel and the Light Novel of F/Z, they are worth your time.

As for spinoffs, there isn't an order to watch them, you can start with anyone you like.
For each spinoff, I've put their seasons and specials in release order. They come from Carnival Phantasm, Today's Menu for the Emiya Family, Lord El-Melloi II, Fate/Apocrypha, Fate/Extra, Fate/Grand Order, Fate/Grand Carnival to Fate/kaleid liner Prisma☆Illya.
