I would ignore those stats. Seriously. Grad schools do not parse so finely the USNWR or relative SAT scores before accepting a student or rejecting them. They know perfectly well that they might find the next Warren Buffet in Oklahoma or Utah as in Harvard Yard. See for example the Harvard Law School list of schools attended by the students it accepted. You can google for it. They range from small religious schools and state directionals to, well, Harvard undergrad.
What matters more is your GPA and GRE and/or GMAT scores, what you bring to the table from your work and/or research, and how you compose your application. Plus who you are as a person and your other intangibles as becomes clear during interview should you have one. So developing your own confident POV about your subject and honing your craft are helpful.
So focus on GPA currently as that’s what’s under your control now. What school would help you achieve your best GPA while also giving you the academics you need?
To my mind the place that makes you happy as a student will help your GPA. Conversely, unhappy students may not perform as well.
Smith is one of the top schools in the country. It is empowering of women esp in STEM fields. Women’s colleges tend to produce leaders disproportionately regardless of the field compared with women who attend co-ed schools. You have several other colleges to branch out to should you decide to do so, including Amherst, UMass Amherst, Mt. Holyoke and Hampshire–and though that college has been going through difficulties lately, they do offer different perspectives on the world. Differing POVs can be very helpful for problem solving–less group think and more creativity.
Best of luck to you.
