I recently installed Ubuntu on a SSD with logical/physical sector size
of 4096/4096. Everything works fine; however, just for curiosity I did
a check on the efi partition 500MB, formatted as FAT32.
I got the following error messages: (See image).
This does not happen on a usb drive with 512 byte sectors.
Everything looks fine when I check with fsck.fat:
fsck.fat 4.1 (2017-01-24)
Checking we can access the last sector of the filesystem
Boot sector contents:
System ID "mkfs.fat"

Here is the output you requested from parted:
