I have seen this complaint before. Other than the Firbolg, Variant human (Observant, Resilient, and soon the XGTE Feats), , The fact is with the standard point buy, +1 is basically the same as +2. That is to say, you can start with a +3 wis bonus. For a monk that means a Wood Elf or Kenku can start with +3 mod in Dex and Wis. Even if you did get a +2 wis, then you'd only have a +1 Dex (max) and only be able to get +3/+3.
If you are using rolled stats, it only matters if you happen to roll even on your highest stat.
