Note that the is a user to user folder, so we are all just other users here. Only a few Adobe employees wander around in here. So from another user here is my attempt.

What exactly is this for? Can I change this to an external drive location?

This is local storage of your Lightroom CC files. You can change this to an external drive if you want as long as it is directly connected and not a network drive,

This is normally used as temporary storage for the most recently used files so it doesn't redownload images all the time. Lightroom CC does not use local files the same way that Lightroom Classic does. The main file lives on Adobe's servers and it makes a local cached copy of that when needed. So when you import files what happens is that it will upload them into the cloud and then it might delete the local copies if it needs local disk space or if you haven't used those images in a while.

The real change with Lightroom CC is that your local files are no longer the master copy of the files. Lightroom CC uploads everything you put into it. The "store a local copy" option simply keeps local copies of all the images so you always have them. For Lightroom they are copies though, not the master files which live on Adobe's servers.

Can you please provide more details on the process. Not developer level, but for the more technically interested person?

You mean the import or migrate process? What happens is that Lightroom CC imports the files and copies them to a temporary area on your hard disk. It will then start uploading everything to the cloud. If it is done with that after a few hours of uploading, it might delete some of the local files if you went over the storage limit set in the preferences. Again to Lightroom CC the local files are only copies of the masters living in the cloud. they are expendable. This causes a lot of deep questions you need to consider with respect to backup and such but that is the way the program works and operates. Everything in the cloud.

Note that if you are more comfortable with the non-cloud way of doing things there is always Lightroom Classic which works like it always has and your local files are the masters.
