Starting Strength on Green

[Caledore]

Given that Green won't have the over-abundance of +Str items that Blue has - what do you think is a good starting strength score to aim for to not be miserable and over-encumbered all the time?

I am leaning Half-Elf Pally, so not terrible starting Str, but not all that good either. Not sure if I should just go all-in with all 20 points, or spend some on Sta or Wis (given how miserably low it is).
