I'm honestly okay with grouping together DuckTales, Darkwing Duck, Goof Troop and Talespin, plus most of those other things you've mentioned, though I'm hesitant to go ahead and include Chip 'N Dale Rescue Rangers in that grouping (human presence and all). Same reason I rule out Quack Pack.
I was hesitant to include the human ones at first too, but, upon re-watching Quack Pack in full, one episode serves as a direct continuation of Donald's Naval service term in DuckTales, in which he must complete the last remaining 24 hours of his term before receiving his proper discharge. What's more is that that episode featured only duck and dog people instead of any humans (though, Daisy did mention Kent in that episode too).
Plus, in other Quack Pack episodes, there were other rare instances of other animal people besides Donald, his nephews, their friend Gustav, Daisy, and Ludwig Von Drake appearing as citizens of Duckburg, showing that, while Quack Pack's Duckburg had become rather human-populated since DuckTales, there indeed remained some of its original kind of residents still living there.
Furthermore, while the TV show showed only humans, the Disney Adventures magazine comics for Rescue Rangers (including its chapter of the Chaos God crossover) featured some animal people in addition to human people, as though they coexisted in the same city despite the show itself not going into that.
And, in re-watching Goof Troop, I spotted an actual human person seen within an animated crowd of dog people at a carnival in Spoonerville.
And in one episode of Darkwing Duck, DW was watching a beauty pageant on TV and all the participants were human women.
And in the Boom! Studios Darkwing Duck comics,
