No one can accurately predict if a given poster here is going to get into the most selective colleges, let alone get merit money from them. Of course, one should try— if possible. As I said in above post, some of these schools automatically include all applicants for these awards and do not permit direct application or lobbying for these awards. One can research the awards and who has gotten them and work on the applications to best showcase features that appear to be the sort that attract these awards or are in common amongst those who have gotten them. But, the odds are very low on getting money from these schools. CMU, last I looked, no longer gives merit money though they may direct accepted students to private award programs. Of course, things change from year to year, so one has to research what is current.
If OP know what the school budget is for the family, and also understands what schools are expecting the family to pay, it comes down to big merit money, if OP is going to be able to go to a private school or to the higher end OOS public schools outside of ones state. UIUC is an excellent school and will be hard to beat for the price. With the resume the OP has, it is also far more likely that Illinois will come up with some scholarships to further lower the cost from sticker price, than the OP will get one of those very competitive scholarships from top schools. It is also likely that a number of private snd OoS public schools will come up with scholarships to rival or even beat UIUC costs, but UIUC may still be preferable if OP is looking at ratings and reputation.
