The High Aldwin
None of the options fit for me. Levels don't apply to NPCs in general.
I separate proficiency bonus from level and HD. They really shouldn't be tied together IMO and is a failure of design.
An "expert" blacksmith might be +10 (via double proficiency bonus), perhaps higher with ability modifier added in, but would have no levels and just 1 or 2 d8 for HD, if any, since HD really only matter for combat...
Otherwise, you can have a younger person with a high proficiency due to intense training, natural talent, or whatever reason. But, in general, I prefer experience (usually coming with age) to be the primary source of improvement in proficiency.
