You want an Xperia. No removable battery (there are almost no "normal" phones with removable batteries) and instead of a popup camera you get a regular front camera in a tiny bezel (so assuming you don't want a stupid hole/notch in the display that's what you want). But they are overall solid phones with excellent DACs and very clean Android. And it's still a mainstream, non-Chinese brand.
The only disadvantage is price, but they target a niche audience. If you can take a deal with headphones or such it's very much worth it.
