It's an unpopular opinion, but my belief is that trying to go all-in on one paradigm is the actual mistake. There's several types of awkwardness that arise when a UI library is strictly declarative, for example.

On Apple platforms, I've had a lot of success in a hybrid model where the "bones" of the app are imperative AppKit/UIKit and declarative SwiftUI is used where it's a good fit, which gives you the benefits of both wherever they're needed and as well as an escape hatch for otherwise unavoidable contortions. Swift's nature as something of a hodgepodge enables this.
