Very short: Zootopia 2 is lovely and has as many little details about the world and everyone within it as the first one. If you enjoyed the first one, you'll enjoy this one.
Longer:
Zootopia 2 basically does what the first one already did: Using the story of a police case to teach people, inside and outside of the movie, that prejudice and stereotypes we learned to believe are often wrong and even more often dangerous. In addition, it also features other themes like stolen land, and that ultimately what makes "you" is your decisions in the situations you're dealt.
(Important) moral of the story aside: Zootopia 2 is as beautiful, maybe even more, as the first one. Such beautiful colors, so many moving parts and animals, such great detail on soft surfaces and, of course, fur.
Thanks to that, Judy (and the others) look even more beautiful and detailed with so many individual hairs and such awesome effects when things get wet.
The same applies to stuff like water in general, snow and sand.
Like in the first movie, so many little details are shown in the world: How different species work together, how different sizes and skills are used and how buildings and facilities are built to accommodate all the different species.
Emotionally the movie is also as lovely as the first one: Many jokes, Judy's overly positive optimism and Nick's cynicism do the same job as in the first one. Only this time the movie actually goes and deals with how both of these traits of them are also used to mask their emotional weakness and how they deal with them. (Although I personally feel Judy gets off the hook a little easy, but well, details.)
And, as is proper after the first one, there's also at least one tear-jerking emotional part.
So, I recommend that movie. The "police story" in it, I think I actually preferred the case from the first movie. But that little bit aside, characters and details are equally as lovely.
I recommend it, and I'm looking forward to Zootopia 3!
