Comparing your list to mine, I was struck by the size of /boot/efi.
The size of mine is inflated by one directory of 288M,
/boot/efi/7cf63543075b47d48d09f1649641c3a1. I don't know what that
is or why it's there. But the contents look suggestive:

My /boot/efi only has EFI in it that is the mount point UEFI boot files.

I think you can delete the /boot/efi/7cf63543075b47d48d09f1649641c3a1 safely.
