Is there a url / shortcut to easily access hide my email from the Home Screen for example? I am tired always having to dig into Settings > iCloud > Hide my E-Mail to look up an email
Try this.
If it's macOS, it gets the URL from Safari, opens Hide My Email in the System Settings, creates a new email address for the URL, copies the email to the clipboard, and closes the app.
Otherwise, it opens Hide My Email in the settings.
