True that Recall collects more than Signal, but copying actual files, browser session cookies / passwords, mailbox content if desktop mail client is used makes more sense if you have access to device. Recall is also not supposed to collect data from private sessions from popular web browsers. I assume for that it uses some hard coded list of exceptions with an option to add your own.

Both should have protected that kind of data with additional safeguards so that merely copying that data without authentication would have no value.

Here is a video demonstration. Snapshots contain window that is in focus not the whole desktop and for exclusions I assume it would just base it on process name + additional parameters (private browser windows have same process name so must be something additional). You can also add websites for exclusions. Here is an article that lists other things that are not being captured like DRM protected content and one time WhatsApp images.

Also from support article:

In two specific scenarios, Recall will capture snapshots that include InPrivate windows, blocked apps, and blocked websites. If Recall gets launched, or the Now option is selected in Recall, then a snapshot is taken even when InPrivate windows, blocked apps, and blocked websites are displayed. However, these snapshots are not saved by Recall. If you choose to send the information from this snaps
