I love this series. I've not watched season 2, which is by western animation studios.
But I can scarcely believe Disney allowed this. They gave the Star Wars license to creative people and let them make whatever the fuck they wanted.
My favorite is The Ninth Jedi, which makes some changes to how lightsaber colors work compared to canon, and then uses it to tell a story and give several moments serious, delicious, impact.

That moment when Kara's saber gained a color gave me goosebumps!
Every episode is worth seeing, but the ones you listed are the highlights IMO. I'd also mention episode 8, it's a little weaker in comparison but stands out due to its animation and more detailed surroundings compared to other episodes.
