"Lost" doesn't have to mean destroyed, like the ships at Wolf 359. It can also just mean it's... lost.
Quite so. But this is the military speaking in militarianese, so there's a distinction between "lost" and "missing" inherent. Or ought to be...*
I never quite understood the finality they were trying to force on Geordi myself either. Seemed a little well, forced... plot-wise that is lol
The somewhat weird saving grace here is that the party doing that forcing, and speaking of "lost", was Dad and Dad alone. He may quite plausibly have had Reasons. Since the character never returns, we don't learn of the Reasons, or the underlying Issues. But
were the character to return, I'm sure it would be specifically because of said Issues!
Was a reason given as to why at that time they fully declared it officially lost?
The thing is, "they" didn't. Instead, Dad claimed that Starfleet "considered" the ship lost, making this statement in such a way that it seemed he was revealing a secret that went against the official stance (which then naturally would not be "lost", but "missing"). Again, we get the impression of an agenda there...

* OTOH, when Picard "lost" the
Stargazer, the court martial may have been specifically because of that. That is, it's no biggie if a ship sinks from beneath you, but if you
misplace her, losing kmowledge of her whereabouts, like Picard did...
