First off, well done, this looks like a good initiative and you've clearly worked hard on it!

My main question is about app size. Once one has fully built an app and is ready to distribute it to users... how does the file size compare to an Electron app?

The only thing that meaningfully contributes to the size of the app is the size of the GUI library libraries. It currently bundles both Mac and Windows, so you can build packages for each and remove the libraries you don't need. It should be around 50 MB maximum.
