Having never built a full product with any of the existing frameworks, take what I say with a grain if salt.

I always struggled with expo and react Native. Never worked how I wanted it to ootb.

http://capacitorjs.com seems quite promising. Mainly because you can use any web framwork, so porting something like cashu.me seems easier.

Never really delved into it though, as a pure web dev, I always get frustrated when I go into the mobile world.
