UB,
it's a yes and and no on the wood fire oven. i have a barrel oven and need to try out fire brick hearth before doing further on it. i also have what's called a black oven that i call dog hutch which i intend to mod - the fire is too close to the hearth which sits above the fire.
i really need to build one of those round ovens "pompeii" but the effort and size puts me off.
i have looked at trying to build in "tandoori" add on but not got anywhere. a "naan" facility if possible would be of interest - particularly if the warm up was quick. warm up being my no 1 downside to wfo - it takes too long in comparison to electric.
