Here's something I just became aware of, and mention it FYI and possible consideration: Google One has an app for iOS on the iPhone wherein you can backup your iPhone for free. it includes 15 GB of storage. Why do this, you might ask, if one can just back up to iCloud? Good question, and I don't have an answer except perhaps the concept of suspenders plus a belt -- extra security. I've not used it yet, but probably will give it a try.
One feature that I might find handy is apparently one can save an email in Gmail directly into Google One. That could be handy as I use Gmail for my email client. More info in the links below.
