Can I store iCloud backup for my iPhone XS in my Macbook pro to restore it from it?
You can't store an iCloud backup on a Mac (they are stored in iCloud) but you can use Finder on a Mac running Catalina (or iTunes on a Mac running an earlier OS) to backup the iPhone and the backup will be stored on your Mac. See the computer section of How to back up your iPhone, iPad, and iPod touch - Apple Support
