Q I can’t migrate fully from an old iMac with its 1TB disk to a new iMac, as that only has 512GB. What could I move to external storage instead?

A Keep plenty of free space on your Mac’s SSD, and aim for a minimum of 100GB or 20%. Anything less and its performance will suffer and it may wear out sooner than expected. With that as a goal, try to migrate all your apps and at least the basics of your Home folder.
