Unless I’ve missed it the OP has not yet provided a budget, which make it difficult to give advice.
In the meantime, I suggest diving into the Canadian unis since they are more transparent on admissions criteria (more stat focused, less holistic) and financial requirements. @DadTwoGirls may be able to provide more information. My '21 kid seriously considered McGill (loved our visit and everything about the school), but covid prevented them from applying.
Once the OP provides more information, we can give more targeted feedback. CS is a remarkably employable field that is agnostic to undergrad prestige. So there are many, many options if the OP is willing to expand their list.
