I'm considering something similar and Lynx did seem interesting. Thanks to your article I think it is indeed a bit too early.

Another option looks like Tauri v2[0]. It also promises iOS, Android, and Web support (as well as a desktop application). The core is Rust which may or may not have the same adoption issues you saw for C++.

I haven't given it a try yet though but you may find it interesting.
