Does "Store a copy of all originals locally" include develop edits, or originals only?

Hi - I use Lightroom (cloud) on an Adobe account managed by my school, so the organisation owns the storage. If my licence is ever removed I lose access to the assets straight away, so I want a full local copy of everything now rather than relying on a recovery window.

What I need:

- All original RAWs on my own hard drive
- My develop edits saved locally too, not just held in the cloud catalogue

Questions:

1. Does "Store a copy of all originals locally" (Preferences > Local Storage) include edit settings, or originals only?

2. For the back catalogue already in the cloud, is Export as Original & Settings the recommended route, or the bulk Export my photos / ZIP option?

3. Going forward, if I work in the Local tab instead of Cloud, do edits write to XMP sidecars automatically for ARW files?

If somebody has an easy solution that would be great
