The closest the Bible comes to describing a flat earth is the creation in Genesis when it describes the firmament. I’m sure most in this thread will be aware they understood that to mean hard dome. But I don’t think the passage contradicts today’s commonly accepted understandings of the world. The Bible’s other descriptions of the Earth are clearly poetic b/c they come in poetic sections & don't contradict today's understanding either.
I could be more open to the solar system model being incorrect (planets revolving around sun, earth 3rd from the sun, sun enormous, stars other suns & they all have their own planets billions of lightyears away, etc.), but won't deny it either. Just open to it.
