In the 80’s, 40% of CS grads were female. It’s what, 18% now?
That isn’t a good thing. It may be that occasional tokenism will put someone or other into an entry level job, but after that, in my experience, quality and productivity determine who moves up and who gets lovely parting gifts.
But we’re way off topic. To the OP:
I only applied to one college because I knew that’s where I wanted to go. You don’t need hundreds of other opinions if you’re satisfied with the cost, rigor, and campus of those you listed. I suspect adding more names to the mix now will mostly make you anxious - I know it would me.
I have no opinion on early decision except that if it limits options then I’d avoid it.
It’s good general practice not to engineer one’s self into a corner.
