Update 2:
Milkfarm
A huge thanks to @ipsedixit @Local for the recommendation, this year for Christmas, we were able to get in our order in time. 
Milkfarm has a nice selection of Cheeses and Charcuterie available for you to pick and choose as you want. They also offer their own special Milkfarm Cheese Board (pre-chosen with 3 Cheeses and 1 type of Salumi for the Small Board).
We chose to order a Milkfarm Cheeseboard (Small) and supplement it with some additional Charcuterie.
Milkfarm Cheese & Charcuterie Combo Board (S):
They normally come on a Milkfarm wooden serving board (and you’re charged a deposit until you return it), but for Christmas it was a madhouse and they ran out of boards.
No matter, the presentation, condiments and selection were excellent!
Idiazabel - Raw Sheep’s Milk Cheese (Spain):
Nice inherent funkiness from the Raw Sheep’s Milk base, but also creamy and mellow enough that it was a hit at the party.
Cantal - Raw Cow’s Milk Cheese (France):
This was the most popular Cheese with everyone, devoured the fastest. 
The firm Raw Cow’s Milk Cheese had an easy, creamy, buttery taste.
D’Affinois - Cow’s Milk (France):
This was a Double-Cream Soft Cow’s Milk Cheese, almost as soft as a typical Brie, creamy and spreadable, but it had more punch and character than a Brie (which is more mellow and smooth).
Calabrese Sopprasata (San Francisco, CA):
This was fine. Lightly spicy, salty. Not the best Calabrese I’ve had before, but solid.
Big Chet Fennel & Garlic Salami (Minneapolis, MN):
(No pics - I forgot to take it, sorry.)
This was the biggest hit at the party: The Fennel and Garlic really punched up the flavors in this Salami, fragrant, lightly aromatic and almost sweet and savory in a way. 
(@TheCookie @attran99 and others.)
They also carry Bub and Grandma’s Baguettes, so we picked some up as well.
Milkfarm seems like a great local Cheese & Charcuterie Shop in the Eagle Rock area that really saved some time for the holiday party (and for any occasion) with their Cheese & Charcuterie Boards. They have a nice selection of Cheeses and were happy to give out samples. Their Charcuterie selection is a bit small, but is sufficient and nice, especially for locals in the area.
We like the selection (and the proximity) of Eataly a bit more, but the Milkfarm Boards they put together with the nice condiments and layout made the potluck really easy (and it looked professional). 
We’ll be glad to return to try out more selections.
