PWAs work well on Desktops, you can install them on Chrome etc and they show up as native apps in Linux and Windows (opening in a chrome window, minus any address bar etc, at least). If you already have a PWA, I don't know what Electron would give you.

You can also ship PWAs on the Microsoft Store and allow Windows 11 folks to natively install them (for an example/shameless plug: https://homechart.app).
