Flashing to Tasmota is only possible on some Tuya chips and from what I gathered a few months ago all the new products were switching to new chips that could not be flashed anymore. It would get you local control over wifi if it was possible on those devices.
The homebridge plugin would just let you add it to Apple Home via Homebridge / Tuya cloud control, it would not get it into Hubitat.
This is the Hubitat Tuya integration, it is a custom user supported integration and the dev seems to be on hiatus right now, but is still merging PR's other people submit. It may or may not work correctly on your devices.
