Think about it: you have the quirky, awkward, naive, wide-eyed female protagonist. They've been stuck in one place all their life, and now have the chance to get out and live their dream? They make a deal with this snarky, morally-ambiguous male character and the two of them butt heads for most of the movie but by the end of it are either lovers or BFFs. Anna and Kristoff are basically just Rapunzel and Flynn 2.0, then Judy and Nick were Rapunzel and Flynn 3.0. Even Moana, Mirabel, and Asha are very blatantly designed in the Rapunzel mold (though the latter two don't team up with a snarky, moral-ambiguous male).
To be fair, Tangled wasn't the first WDAS film to have the quirky, awkward, and naive female protagonist. Ariel technically would be part of that mold too from The Little Mermaid (which coincidentally had the same directors as Moana). Beauty and the Beast also had the morally-ambigious male character butting heads with the main female before becoming lovers with the Beast. Aladdin even does both with the naive sheltered female Jasmine and the morally-ambiguous male Aladdin, with Raja being a hooved animal acting like a bit of a dog. This isn't something that's exclusive to their newer films.
At the very least, it wasn't exactly intentional on the director's end according to interviews.
Frozen co-director Jennifer Lee did explain how she approached writing Anna here and no where did she say Tangled influenced her:

She says at one point: "It’s funny, I think there are a lot of things where you have to let it go a little at times, kind of let it run its course. But I always think what it means is you have to learn to say it better. I think the best example of that was Anna. I wanted a girl whose only journey was sort of coming-of-age, where she goes from having a naive view of life and love--because she’s lonely--to the most sophisticated and mature view of love, where she’s capable of the ultimate love, which is sacrifice. And that was all I wanted for her. But people really went into more of the dysfunctionality--make her more co-dependent, they wanted to make her a little bit more like Vanellope in
Wreck-It Ralph. And I didn’t have a reason why not to do that, I just couldn’t articulate it yet."
So seems the Disney higher ups actually were trying to push Anna to be like Vanellope rather than Rapunzel.
Zootopia isn't really a fairy tale plot the same way as those other three movies, being more in a modern setting. Co-director Byron Howard said he was more inspired by Robin Hood and the movie came from "desire to create something different from other animal anthropomorphic films, where animals either live in the natural world or in the human world".
This article also does show where the inspiration for Moana really came from:

Encanto co-writer Charise Castro Smith has said that the intention for Mirabel was to "distinct, imperfect, and completely human character" as mentioned here:

If the 2010s onward WDAS movies with female leads really are attempts to cash in on Tangled, by that logic do you think stuff like Beauty and the Beast, Aladdin, Pocahontas, and Mulan from the 1990s were trying to cash in on the success of The Little Mermaid? The fact they left The Rescuers Down Under (which was the only 1990s Disney animated movie that wasn't a musical or having a romance involving teens/young adults) out in the dust doesn't help either.
