Who knows. HomePod can be a hub as well as the other two devices you named but so far there have been no other options. Good for me I have several of each so no issues controlling things around the house when away. If nothing else you might consider a used Apple TV or something they really are good devices.
Problem is we don’t have a HomePod or a TV! Watch TV on our Macs with Plex or a streaming service.
