Alcohol is the clear winner as a boring, non-specific gift for pretty much any adult function (maybe no t funerals). Some other low-risk housewarming gifts could be a house plant, candles, or a cheese board arrangement. Decor and functional items are tricky because you don't know their taste or needs. It's easier to stow a bottle of wine in the back of a cabinet vs., idk a giant LIVE.LAUGH.LOVE sign, and there's no pressure to display it. But if you know her and what she might like then idk lol get that thing.
