What you are asking can only be achieved by something integrated into the OS. Thankfully we have Seedvault.
Seedvault is a backup system that doesn't have a standalone app, but integrated into many ROMs, and accessed via Android system settings. It does daily encrypted "low level" backups, primarily to a USB storage, or some other medium of your choosing. Seedvault comes with many ROMs, including Graphene, e/OS/, and Calyx.
It also works with Nextcloud 😀

Heads up: Seedvault uses Android's system wide backup API. This API allows apps to opt-out of system wide backups if they choose, which is often used by messaging and banking apps for user data to not end up in Google servers.
In my case, I set Signal messenger to backup into a specific folder where it keeps backups of last 2 days. Then I use Nextcloud app to sync that folder.

@Bene@fosstodon.org I am aware that this doesn't really solve your problem now, but at best can guide you which phone to choose next time. I would say, use Nextcloud with DAVx5 for full contact and calendar syncing. Some launchers allow exporting their settings. I know Lawnchair, Nova, and Niagara launchers have backup/export options.
