Since the add-on is new, not too many pictures are online of what each option looks like furnished, so there was only one option for me left to do: do them all! It was time consuming, but well worth it as it gave me the option to see the rooms fully decorated and then plan accordingly.
With that, I settled on the design:
East: Kitchen
West: Enchanter's Tower
North: Storeroom
I finished up my house last night and it looks great. I didn't elect to use every option (put the enchanter on the second floor rather than in the tower), because I didn't want a house too crowded with barrels and chests, but I'm pleased with it.
My newly acquired daughter thinks so, too.

One of these days, I'll actually finish the game.

Tonight, I'm off to do a few quests with Lydia and pad my gold reserves. Once I feel confident enough to explore on my own without a decoy, she'll become my attendant. I
need that carriage at my house, dang it.
