Also, a lot of the really fun pieces to decorate with (wall planters, riviera shelves, etc.) are pretty low level for crafters, and of course you'll get xp for crafting them, so it's really also worth slowly levelling your crafters to decorate your house (provided you or someone in the FC is interested in it).

Definitely suggest a chocobo stable. They're not too expensive, but again, make sure you're checking the price on the MB vs the price at the housing merchant bc there's no reason to pay extra.
