WiFi transfer in your share options.
I don't personally know about the moto or the LG but some data can be transferred USBC to USBC and using a file manager. That takes a cord or an adaptor that you may not have.
Cloud storage. If you have a Google account then you have cloud storage that you may not be taking advantage of in Google Drive and Google Photos, which I believe uses Google Drive. If you aren't using Photos and don't have Drive both are free, Photos should have come on your device, Drive is as easy to set up as signing in to it from the app. Then not only will you have the full size full photos and videos but you will be able to view or access them from anywhere you can sign into Google. Plus it will automatically backup folders that you select and never again will you have to transfer photos from one device to another, as they will all show up when you sign in. It makes sharing items easy too.
DropBox is another cloud storage solution with similar features.
