iPhone Restore from backup - lose current iOS?

Are you sure about that? AFAIK the backups don't store OS data, only user data, so you can take data from an old backup onto a new OS without it downgrading the OS
Similarly, you can't use a backup made on iOS 12.2 on a device running 12.1, because the data may not work on the reduced feature set, and the OS data isn't there to upgrade at time of restore.
I’m pretty sure. I restored my backup from iOS 12.1.4 and it automatically upgraded to 12.2. The only way to avoid upgrading that I can think of is if you downloaded the ipsw file, but even with that, Apple is no longer signing 12.1.2.
I agree with the second part of what you said. Most times you cannot put a new backup on an old iOS if you’re trying to roll back or whatever is the case.
It should tell you if I’m not mistaken, however I cannot guarantee it.
