I was in your shoes not long ago, and ended up going with
https://pelicanflightschool.com/ They’ve got a full program that’s literally built to take you from no experience to commercial level, including the CFI step if you want to build hours. It’s in South Florida, so you’re flying year-round, which is a big plus. What really helped me was that they assist with F1 and M1 visas, and they’re used to working with international folks. Prices are transparent too, and they’re running a deal now because of their 40-year anniversary. Definitely worth a look.
