Python, along with C++ enjoys the benefits of Qt. You can build great stuff with cross-platform Qt. And it won't be webview(Electron / Tauri) based.

What would be the benefits of this? I can't think of any yet.

I worked on a team the switched v2 of our product from Python + QT to Tauri specifically to get away from QT. If you have any kind of specific design requirements, QT is pain. The ability to use the frontend web stack is a huge win especially for a team that already has frontend developers.

Rust was a nice bonus.

Doesn't qt also offers a webview solution?

It’s very basic. Good enough for oauth flow but not much beyond that, definitely not to host your entire UI. Also I don’t see what the point of that would be.

This benefits people and teams who prefer to build UIs with html/js/CSS.

Avoiding Qt licensing

Quite a few options there. Never really a problem.
