I haven't played skyrim in a while so I can't remember specific dungeons or anything (it doesn't help that Bethesda did a wonderful job of making every dungeon feel and play the same... &--#62;_&--#62; )

I want to test how my mod works against higher-level encounters and enemies, especially those that wear heavy armor. The problem with simply setting my level to 50 in-game and going to the nearest dungion to riverwood is that while the bandits that spawn there are going to be higher level, they still wear low level gear, require me to find such dungion in the first place, and being that its so close to riverwood they aren't exactly going to be that much higher level anyways.

So with that all said - dungions I can use the CoC command to get to, that would have apropreately high level and (hopefully) heavy armored enemies to test against?

Skyrim enemies practically never have good armor, and even if they did they don't have the perks for it.

Dundeons up North are usually more difficult. Think about quests that you get when your character moves along. Boethia's followers, for example, is only possible after you reach level 30 or so.. Set your chateacter to that and go to that area (east of Windhelm) .

Also could look at tables in creation kit to get names of all dungeons - select some from the appropriate northern areas.
