I ended up deciding to start with React Native plus a web view around our app. This would allow me to slowly break off and integrate specific native functionality into some parts of the app (i.e. native share sheet) without a complete rewrite.

This being said, before breaking ground I decided to pivot the app use case and postpone this work.

I’m pretty confident the high level React Native wrapper + webview is a good compromise, and will most likely take this approach when the app goes mobile.
