What plant should I get?

Hi everyone! I need advice on what plant to put in my shower 🥰
My bathroom has one small north-facing window. The plant has to be completely safe for pets and toddlers and not messy (I hate picking up dropped leaves!!). I really want it to be varniganted and it needs to have flowers that smell good.
Would this one work? I found someone selling cuttings on etsy for only $38 each and it sounds perfect!!
