I'm not tourer but at 5' tall (short?) I know the struggle is real to find a proper sized bike lol. There are small touring bikes though List of XS Touring Bikes for Smaller Cyclists: 42cm, 44cm, 46cm - CyclingAbout

Hybrid usually have a longer ETT than roads bikes so the reach would be longer than on the equivalent size road bike.

Perhaps she could "upgrade" to one of those when she's more into it. As other, I'd also recommend riding the Vita as is, maybe add bar ends.
