My first spell would have to be the cantrip Fist.
I might pick up Door along the way, for the AC.
Oh and Magic Missile.
In a rolled stats world it is easy to get away with things like this vs standard array or point buy where you get cookie cutter builds and races. I do rolled stats in my game different than the standard way to close some of the random roll gaps between players
yes but your AC is going to be all kinds of terrible and you still don't have hardly any weapon options. I'd go 14 Str and 14 Dex instead of 16 Str and 12 Dex.
I'd go Divination or Abjurer
