I think Cinestill would be a good bet as 1) you can up to 1600 and get usable photos without pushing (IMO, YMMV, if you're careful, etc.), and 2) I've found more than just being tungsten balanced, no matter what kind of shitty artificial/mixed lighting I've shot it in the results were really easy to work with (compared to Portra 400 which is the main other film I've abused the same way).
