I’m not exclusive to PWA and Xamarin; React Native is huge right now and Google is pushing Flutter heavily (in order to ease the transition from Android to Fuchsia, but I digress). And Swift/ObjC with Xcode and Kotlin/Java with Android Studio are always solid options and the ones Apple and Google officially recommend if you ask them.

The stacks and options are just tools in a box; I believe in using the right tool for the job (or the tool required for the contract) rather than being a tool about this stuff. But if asked my opinion I will default to PWA until I know there's a feature requirement beyond PWA's growing abilities.
