Trouble restoring hard drive space after deleting bootcamp partition
The HDD part of your Fusion Drive contains an alien EFI partition:

3:                        EFI NO NAME                 104.9 MB   disk1s3


This second EFI blocks restoring a full sized container:


Get the details: diskutil list
Remove the NO NAME EFI:

diskutil eraseVolume "Free Space" %noformat% /dev/diskXsY #replace with the device node of the NO NAME EFI (in your example disk1s3)

Get the APFS container reference of the APFS container spanning the two physical drives: diskutil ap list. (In your example disk2) 
Resize the container:

diskutil ap resizeContainer containerReferenceDevice 0


with containerReferenceDevice = disk2 this is:

diskutil ap resizeContainer disk2 0
