web apps make a lot of trouble if they are in daily business because of much browsers & versions.
disadvantage of web pages, they are time expensive and cost in development and need much care just at that moment.
you have very limited access to the native os from website.
web apps need a web server hosting and online connection. what happens if the user not have a online connection.
webview seems not having cookies for login.
privat i used/tryed ms visual studio 2017 with web forms (code behind), web api etc & database with my isp and a web hosting contract. (vs 2017 also contains setup for xamarin.)
but i like real desktop apps much more. its more fun in development.
you should first think about what is required urgently in your app, and then choose the tool.
look also for B4X XUI
as MikeH said, nobody need a app that it is just a browser inside.
i know that people use windows universal app with browser component for her html app for xbox one ...
