In the early Patristic period, some Fathers taught that Scripture was silent on the question and believed (as a matter of science) the earth is a globe. A few thought Scripture taught flat earth. From the time of St. Bede, who used a globe earth model for calculating the date of Easter, there was a consensus among educated Catholics that the earth is a globe. St. Bede went so far as to claim that globe earth was supported by Scripture. St. Thomas Aquinas, however, while explicitly teaching (as science) that the earth is a globe, merely believed that there is nothing in Sacred Scripture that conflicts with this. Throughout the medieval period, globe earth was the official position taught in the Catholic operated university system, but as a matter of science not religious doctrine.
I have written many posts in this subforum giving quotes and references that establish these points. If you are interested in seeing these, I suggest using the forum search function to find these.
It would be difficult for the Church to condemn globe earth since that was the position held by educated Catholics for most of our history, including Fathers, Doctors and Popes. There is nothing comparable in regard to heliocentrism.
Ven. Bede believed in a solid firmament separating the waters from the waters and with the stars fixed within the firmament which he theorized to be a kind of ice:
“Described in these verses is the creation of our heaven in which the stars are fixed. It is established that the firmament is in the midst of the waters, for we understand that waters were placed beneath the firmament and in the air and the land; and we are taught about the placement of these waters above it by the authority of this Scripture passage and by the words of the prophet who said, “Spreading out heaven like a tent, you cover your chamber with waters.” It is in agreement then that the starry heaven was firmly set in the midst of the waters, and this does not prevent the belief that it was made from these waters.
We know the great strength, purity and transparency of crystalline rock that was made by the congealing of the waters. What could keep us from believing the same arranger of things of nature solidified the waters into the firmament of heaven? But if it disturbs one how the waters, whose very nature is always to flow and to settle to the lowest point, can settle above heaven whose shape we know is round, let him remember the Scripture saying of God, “He binds up the waters in his cloud, and the cloud is not rent under it.”One may understand, furthermore, that the one who binds up the waters below heaven, when he wishes and occasion arises, supported it without a foundation of firm matter and sustained it only by the vapors of the clouds, so that the water does not fall, is also the one able to suspend the waters above the round sphere of heaven, not with some tenuous vapory mist but with the solidity of ice, so that they would never fall. Even if he willed these liquid waters to remain fixed, would this be any greater miracle than “he hangs the earth upon nothing,” as Scripture states?”[1]

This diagram shows how the heavenly bodies would be in the firmament.
(I don't necessarily agree with their conclusion in the notation here. How do we know there isn't water above the stars?)

Ven Bede says Heaven is a round sphere. When we moderns hear the word "sphere" we automatically think of the Blue Marble photo, which was manufactured by computer artistry,
(there are no actual photos of a ball earth) with upside down people on the bottom.
Yet sphere, or globe can also be consistent with Ancient Hebrew cosmology. The use of the word round can also apply to this model.

Bede explains the waters above and the waters below and I'm not sure if he is referring to a ball earth or a sphere with the flat earth inside,
however I have never seen a modern ball earth model that accounts for the firmament and the waters above and waters below.
That's what I was asking about in my earlier post.
