You are a very strong applicant. Congratulations on your excellent results in high school. I know that this took a lot of work.
And by the way I think that the difference between unweighted 4.0 and unweighted 3.98 is probably a single “-” sign somewhere among all of your A’s. I do not think that this matters at all and I do not think that it will have any impact on your admissions results.
Even with this, as others have said UNC (out of state) and Dartmouth College are reaches, and Wisconsin is not a safety. I hope that UMD is a safety for you being in-state with such excellent stats. However, you should make sure that it is (your guidance counselor very likely knows much better than I do) because I do not see any other safety on this list.
To be honest without looking on-line I could not tell you which of UNC or UMD or U.Wisconsin is higher ranked for your intended major. However, they all are very good in general and for the majors that I am familiar with. UMD is a very good university and is likely to be more affordable since you are in-state. Since you have a major where some form of graduate work is entirely likely, make sure that you consider this additional expense when you and your parents figure out what your budget is.
Also, while Dartmouth College is excellent and highly ranked, IF you get in (which is of course more likely to not happen), it is not a good fit for all students who can get in. It is for example in a small town in a rural area with cold winters (since I am originally from Montreal and have a daughter who studied in Vermont I might call these “real winters”). If you get accepted, then make sure that you want to work that hard in a small school in a small town in the bitter cold before committing.
You can get an excellent education at any school on your list and can do very well with a bachelor’s degree from any school on your list.
Best wishes and I am expecting that you will do well regardless of which of these four very good universities you end up attending.
