Disney Plus has it all.
The animated movie is meh, okay. It introduces the character of Ahsoka though. She really starts off as Anakin's bratty padawan and really does not grow up and become a respectable character until about the 3rd season.
The clone troopers Rex, Cody, Fives, Heavy, Gregor, and Jesse are worth noting. Their stories really fill out during the course of the series and culminate at the end of season 7, which coincides with the end of the Clone Wars and Order 66. Ahsoka, Rex, and Gregor also show up in Star Wars: Rebels; those stories lead right up to the Rogue One movie.
The series as a whole does have some tedious story arcs, but all of it goes better as the seasons progress and each character's story becomes more complete. The Bad Batch is really a spin-off of a special group of clones that is introduced in one of the later seasons. The Bad Batch is not essential viewing at this point, but a good spin-off story. With the tie-ins to Episode II, Episode III, and Book of Boba Fett. I would consider the later seasons of Clone Wars to be highly recommended to help give more depth to the main storylines.
