You have to understand that the PoE dwarf is different from the D&D dwarf. PoE dwarves are still tenacious and have a propensity for being pragmatic, but because of the way the world of PoE works (also, the current cycle isn't as old as many D&D settings) they're more known for being explorers and trailblazers rather than builders.
Think Aragorn, subtract height, that's the typical PoE dwarf. Beer guzzling/grumpiness/aloofness is optional. Boreal Dwarves are basically the northern variety, at home in snowy wilderness areas.
Nothing wrong with a dwarf monk mechanics-wise, and story-wise it makes sense that a wandering dwarf would also be some kind of ascetic. Feel free to pick any background/origin, though from your description an Ixamitl Plains Philosopher or White that Wends Explorer make sense. A few points in lore for scrolls is always nice to have (at least 4 for Scrolls of Protection/Defense), and around 4 points in Athletics/Survival is always useful for any physical combat character. You can dump the rest into Survival, Stealth or Mechanics if you want.
From your description, Mig: x Con: x Dex: 14-16 Per: 14-16 Int: x Res: x makes sense from a dialogue perspective. You need good Perception to open up many of the subtle/wise dialogue options, and IMO you need at least 14 Dexterity to be considered "nimble". That should leave you enough points to develop your other stats, as other people have advised.
There's no measure for actual wisdom outside of how you employ your options. If you want your character to be talkative, just avoid the Stoic disposition.
