We've used USMT for User Profile Migrations for years. We run USMT with USMTGUI from Ehlertech, or more frequently these days we use their User Profile Central.
It is basically a GUI utilizing USMT. It is however professional SW so you must pay for it. But as it is quite cheap, is simple to use, and includes premium support it really is an easy choice.
USMTGUI is updated to the latest Win 11 edition and has, since autumn 2019, been capable of migrating favorites etc. for the new Edge Chromium. Also the latest corporate versions from Autumn 2019 onward migrates profiles to Azure
Regarding Favorites from Edge, Chromium Edge, Chrome and Firefox, and Chrome and Firefox credentials, they are easily migrated with USMT.
The reason you cannot migrate Edge and Chromium Edge credentials directly, is that those credentials are stored in the "Credential Manager" and they're not supposed to be able to be copied. - If they were, the credential manager wouldn't be worth much ;-)
To migrate Credentials stored in the "Credential Manager" you basically need to export them, for instance to desktop, logged in as the user. Then move them over with USMT, along with the users data and, import the credentials after logging in as the user..
