Just for closure, have succesfully migrated data/addons/settings from the Vero 4k+ to stock Kodi 19.5 running on WIndows 10 22H2 by using the official Backup addon with the settings in the screenshot below. All it took was a restore on the Windows device for it all come back, with the databases being rebuilt on the fly. As a caveat, did have errors when databases were backed up and restore, so chose not to have them restored and have Kodi on Windows rebuild them. I’d also set up Trakt synching for synchronization of content and watched status across both installations, and they work fine.
Leaving this here but closing the thread in case anyone’s attempting this in the future.
