Hi all-
I have an iCloud backup of my iPhone 7 with a "Last Backup" date of 11/13/16.

My current iOS version is 10.2.1.

I want to see if it's possible to revert to an earlier version of iOS from my iCloud backup. Perhaps the Last Backup mentioned above is earlier than 10.2.1..?

And so my question is, if I restore from that iCloud backup, will it place me on the version it was during that backup?

My fear is to lose the 10.2.1 ver. and somehow get stuck with the latest iOS. So I figured it would be safer to ask the experts here before I screw something up!

Backup only contains data essentially, it doesn't contain iOS itself, so it can't be used to jump to different iOS versions or anything like that.

Backups of iOS devices do not back up the operating system, but instead only back up user data. If you have to restore from the backup today, you'd be restoring to 11.0.3. There is no way to revert to an older version of iOS, or even 10.2.1.

Wow.. thanks. I'm also reading that a factory reset will place me on the latest iOS as well, but this didn't happen to me. I have a brand new iPhone 6S on 10.3.3, which I've already factory reset and installed backups to, but yet I'm still on 10.3.3.

Resets and restores are different things.
For now, Apple is still signing 10.3.3 on the 6s only, so it’s still possible to restore that, but you can expect the signing window to close very soon.
