It seems you're not the only one who struggles. I love the Haindl and it's one of the first decks I bought, but the court cards are difficult for me, too. I'm glad they appear rarely when I read with them... because I find the attributions confusing and even counter intuitive.
The mythological figures turn the court cards for me into something more resembling an archetype - i.e., a different set of trumps. They lose their "oh that's my knight/disks stubbornness"-potential. And that's a pity.
The Haindlcious blog makes it sound like an advantage but that doesn't really convince me. For study that may be great and give new insights about the character of each suit, but for readings, I find it an obstacle.

The only place where I can "dock on" with more human interpretations was the Daugther/Cups because it's said that's a portrait of his wife. Haindl himself was obviously able to see the court card, the goddess Bridget and a concrete person all in one. And the portrait character of this specific card makes it easier. But most of the other court cards? They're too far removed from the mundane humans and their characteristics that appear in other decks as courts
Benebell Wen talks about the attributions of court cards, too. Did you see her review?

She likes the multiculturality of the court cards, and in theory, I do so, too. But in order to use them, you have to "learn" them: Kali, Odin, Spider Woman. At least to know who they are and what they stand for. And who feels an equal degree of closeness to so many different traditions? It throws the court cards out of balance for me. Which is a challenge, of course.
Well, the whole Haindl deck is pretty abstract, and you have to react to the images. There's little narrative to guide you - especially if you are used to the RWS scenes with their backdrops, props, symbol and story enacted on each card. Actually, the mythological courts give you some sort of narrative. Which should, once you know them well, make reading them easier than the pips. Nevertheless, I find them more difficult.
I read them more as deep character traits or affinities than as concrete persons. That option doesn't work for me with the Haindl.
I'm really sorry - that wasn't very helpful....
