The seed for this topic was sown by Ian at our meeting on October 13th 2022. I had to admit that although I had a reasonable idea of what happened with Google Photos, I was unsure what happened with Apple’s cloud offering.
I was reasonable quick in advising (and it’s reported in the notes of the meeting), that as expected …
“I can confirm that deleting a file on iCloud Drive from the Files app on an iPhone will delete it from icloud.com and your iCloud drive on MacOS as well – which is what you would expect should happen.”
However, the situation of Photos stored in the Apple Photos app (on iPhone or iPad) and iCloud Photos should also be noted – for completeness.
I’m not going to write anything; just provide three links to follow to clarify …

and
How to recover a deleted photo or video on your iPhone or iPad
If you want to delete a Photo from both device and iCloud Photos. Just ensure Sync is left on and then you can delete the image from either the device or icloud.com
Having confirmed all this, and having more storage space on iCloud, and understanding that sharing Photo Albums is about to come to Apple Photos, and having checked that Sync’ing does seem to be working for iCloud Photos (from my Apple devices), I checked my Google Photos settings settings and switched-off Back up and Sync. I was doing far too many cloud backups!!! Always worth checking. If I want a Photo to be on Google Photos (for sharing for instance), I will now Upload, not rely on syncing.
