It came from Apple with a Fusion Drive as the 2019 27" iMacs did not come with a 2 TB HD option. What has happened to it in the past 4 years is anyone's guess. Why do you ask?

The OP asked "How do I know if it’s an SSD or Fusion?"
According to the Technical Specifications, a 2 TB Fusion Drive was standard on the 3.7 GHz model, and a built-to-order option on the 3.0 and 3.1 GHz models. A 2 TB SSD was a build-to-order option on the 3.7 GHz model.
If the OP brings up a System Report it should become obvious whether the Mac has.a Fusion Drive or a SSD. The Storage, SATA, and NVMExpress sections, together, should be pretty enlightening. In Ventura, you can get to the System Report
Hi stlgasman1,
It looks like the iMac currently doesn't have a Fusion Drive, but it might have shipped with one earlier as mentioned by rkaufman87.
Whether that single drive is an SSD or a spinning hard drive, I'm not sure.

FWIW, "/dev/disk1 (synthesized):" indicates you have a Fusion Drive.
FYI, this does not indicate a Fusion Drive. The synthesized part is in reference to the APFS Container on the physical drive "disk0" which is actually mentioned for "disk1" (line 0) which says "APFS Container Scheme - Physical Store disk0s2".
A Fusion Drive also has a somewhat similar line...I forget exactly how it is listed, but usually there will be a virtualized remnant unless the hard drive has failed and the SSD has been erased.
Edit: If the 2TB drive is an SSD, then this iMac never had a Fusion Drive (assuming all drives are from the factory). If the 2TB drive is a hard drive, then there is a slim possibility this could have been a Fusion Drive, but it is much less likely for an SSD to disappear completely, although it is possible.

Glad you think so. Of course none of my APFS formatted SSDs on any of my Macs have a "synthesized volume" listed. Only my Macs with a Fusion Drive.
3 of mine have it...
1st is the internal Fusion Drive...
/dev/disk4 (synthesized):
#: TYPE NAME SIZE IDENTIFIER
0: APFS Container Scheme - +1.0 TB disk4
Physical Stores disk3s2, disk0s2
1: APFS Volume Macintosh HD 11.2 GB disk4s1
2: APFS Volume Macintosh HD - Data 673.0 GB disk4s2
3: APFS Volume Preboot 84.4 MB disk4s3
4: APFS Volume Recovery 529.0 MB disk4s4
5: APFS Volume VM 2.1 GB disk4s5
2nd is an external TB3 SSD...
/dev/disk5 (synthesized):

0: APFS Container Scheme - +1.9 TB disk5
Physical Store disk2s2
1: APFS Volume Ventura - Data 1.3 TB disk5s1

4: APFS Volume 9.2 GB disk5s4
5: APFS Volume Update 1.3 MB disk5s5
6: APFS Volume VM 1.1 GB disk5s6
3rd is an external USB3 SSD...
/dev/disk9 (synthesized):

0: APFS Container Scheme - +2.0 TB disk9
Physical Store disk8s2
1: APFS Volume SSD5slow - Data 1.2 TB disk9s1

4: APFS Volume Recovery 1.1 GB disk9s4

6: APFS Volume Update 917.5 KB disk9s6
FWIW, "/dev/disk1 (synthesized):" indicates you have a Fusion Drive.
Just to add if you are running Monterey or earlier, About This Mac > Storage will show if you have a Fusion Drive…
Here is a screenshot from my MacBook Pro 14" M2 laptop running Ventura:
Run the following command to get the information about the physical drive:
diskutil info disk0
Note: The last character is a zero.
In Ventura, check System Settings > General > Storage. It should indicate a Fusion Drive or not.
I'm jealous. 😎
