Cycads have palm-like leaves though, so veeery different! I’d say baobabs are not too different in their growth habit from other Bombacoideae (Malvaceae). Compare with e.g. Ceiba, Pseudobombax, Cavanillesia. And the leaves look just like most Malvaceae plants as well ;)

Fun fact: Pseudobombax trees can actually do photosynthesis with their trunk, which is green (or at least has green streaks).
