Have you considered Qt?
As a Mac user I prefer native applications if available. But still, I would consider a well-written Qt application.
For example, qBittorrent is quite alright.
Are there any modern applications / examples built with Qt? This is the screenshot from the Wikipedia article:

I always see Qt mentioned, so I'm definitely not trying to discredit it. I just never seem to see common examples with it compared to something written in Electron.
