Personally I think web UI via WebView2 is the only way forward; Chromium is far and away the most powerful UI framework shipping with Windows these days. Even if "native" UI frameworks were doing everything right, it's hard to compete with all the investments in Chromium.
P.S. WinForms isn't dead; it's maintained by the .NET team and it gets a lot more attention than WPF. But, well, it's WinForms :)
