Beside the ML/AI sub-community, I am having a hard time finding GUI innovation in the Python ecosystem. Perhaps, you could show me an option that doesn't suck? I've tried Kivy, PyQt, PySide, Eel, gooey, etc... I am not a JS dev and had an electron/react app up and running that I easily ported to my Android phone in under an hour.

On one hand you have the complex licensing thing (PyQt) where you are limited to desktop of Mac, Win, Linux. On the other you have a skill (JS dev) that is good for literally any screen, on any platform with almost zero complications for commercial apps. It is a no brainer.
If it isn't obvious, I have begun the transition to embrace JS for what it is... I am learning it and it hasn't been too bad. Python will be relegated to ML/AI and glue...
Regarding licensing, you can simply buy the commercial license only when you go public / begin making money. It's not that difficult I think.
But as I said, you are correct in that Electron is easier to use for many people. I'm also the last person to say you should always use PyQt. Just today I recommended someone to use Electron over PyQt. It really depends on the project.
