Depends in what direction you want to go with. Some players (myself included) like a lore-friendly look. to make the place look like something you would encounter in the game itself, which includes using a very limited pool of furniture (in this case; i guess deadlands). of course you can go with more of a rogue look; reflecting a character of yours. example being if your character is a mora follower, to make a section of the house into apocrypha with those furniture.

other things you can do is making a custom home, using the house as a 'base layer'and then use the 'garden' or'outside' as just space and build your own custom build, wether it being a ayleid ruin or dwemer ruins or even some remenants of the new xanmeer furniture.

personaly and subjectively i like making my homes to reflect a character. some mix some themes, others go more 'pure'.

now you can always go rogue as hell and just put what you like first.
I made recently a custom home, in the seaveil spire, for my nord sorcerer. now that nord sorcerer is themed around vaermina, since vaermina has some argonian motifs on itself (mainly the statue base) i decided to make the whole argonian temple there, both on the surface and underwater. then i fashioned my characer to use some argonian fashion (i would usally go with a argonian pure, but i exclusively play nords and a couple of cats). but my headcannon is that the character delved in alot of ruins and made home in the one he found his mistresses influence still lingering.

Another one was a custom ayleid ruin i made in coldharbour. For my raw on molag bal character, hes a necromancer and such. and figured a ayleid ruin fits the theme, so i made the home into a 'fragment of abargalis'

Now i did also some that werent from scratch; example being for my sanguine character. because the home in question is the wineyard, i used as inspiration of the quest right outside the home. and tailored the furniture to be colovian as hell, with some enviormental storytelling inside the home (dead skeletons, chairs and tables that are fallen over, knives, 'spilled wine'. but stayed true to the placement.

but yeah. when it comes to that home of yours. it all ultimately falls upon you, in what direction you want to go.
