Building a wheelset for my 1993 Specialized Crossroads gravel build… need advice.

I’m thinking Mavic A319 rims. With either 32 or 36 spokes. I need help picking which spokes and hubs to use though.

For spokes I was thinking Sapim Race Double Butted

For hubs I was thinking Shimano XT or Tiagra

Is this setup overkill for an all around gravel bike? I’ll use the bike for some off-road/gravel, some single track, the occasional bike packing trip, and some commuting.
