Ponytail plant ( Beaucarnea recurvata) is a good choice..it enjoys very dry conditions. If you cannot find a tall mature one at this time of the year, consider a smaller version of it, then maybe use a taller plant stand, so it gives it height. But it is a very, very slow growing plant. Needs watering but with good long intervals, so be careful with watering, even indoors, even with a furnace. It is so efficient in stashing moisture in its trunk. Typically this plant ably handles our driest hottest temps here in my area during the warm months outdoors when our temps soar way past 100F. I hope that window with a furnace is a south facing window. Otherwise, you may even need to augment its growing area with grow lights.
As for Yucca, I would not recommend that...it is such a high light level loving plant. It will just suffer indoors. It maybe drought tolerant too like Beaucarnea recurvata, but its growth habit demands better, higher light conditions.
