I think it’s pretty good to keep it in mind that heliocentrism is literally speaking just a change in what coordinate system you use, but it is legitimately a much more convenient coordinate system.
For everyday life, flat earth is more convenient than round earth geocentrism, which in turn is more convenient than heliocentrism. Like we don’t constantly change our city maps based on the time of year, for instance, which we would have to do if we used a truly heliocentric coordinate system as the positions of city buildings are not even approximately constant within such a coordinate system.
This is mainly because the sun and the earth are powerful enough to handle heliocentrism for you, e.g. the earth pulls you and the cities towards the earth so you don’t have to put effort into staying on it.
The sun and the planetary motion does remain the most important governing factor for predicting activities on earth, though, even given this coordinate change. We just mix them together into ~epicyclic variables like “day”/”night” and “summer”/”autumn”/”winter”/”spring” rather than talking explicitly about the sun, the earth, and their relative positions.
