A few tips for the errors you're hitting:

• DynamicEventPayload.cpp will need to be forked so that we can patch the type conversion error. See https://github.com/microsoft/react-native-windows/wiki/Integration-Process#overriding-files--errors-in-reactcommon for info.
• Run yarn ling:fix to fix the prettier errors
• It looks like some files in @react-native/tester have changed upstream. Unfortunately the integration script doesn't automatically update those files for us, so we have to do it manually. Making those updates should resolve failing yarn validate-overrides command.

• The TextInputChangeEventData type was changed from export type to a non-exported type, which removes it from the public API surface. Please re-add export to maintain backward compatibility for consumers who reference this type.

type TextInputChangeEventData = $ReadOnly<{

packages/@office-iss/react-native-win32/src-win/Libraries/Components/TextInput/TextInput.win32.js:114

• The TextInputFocusEventData type was changed from export type to a non-exported type, which may break code relying on that export. Restore export to preserve the public type definition.

type TextInputFocusEventData = TargetEvent;

Left one small comment to address. Otherwise looks good, great work!

If you want to remove the DeviceInfo.win32.js fork you'll need to delete the file, call npx react-native-platform-override remove to remove the override and then delete this line
