I don't see Meghan as a strong woman, I see her as a master manipulator.
Meghan uses people to get what she wants, and she is okay with lying to get what she wants. Her role on suits was thanks to her co star, who she knew for years and who lobbied for her to get the role of his love interest. She lied about having a union card to get an earlier job. She used her Royal wedding to open up doors to people she could never have dreamed of being in their orbit. Using her Royal titles to progress her profile outside of the RF.
There is so much more, the things coming out now about her orchestrating her meeting with Harry, the ex partners who were unceremoniously dumped for the next step up,
Even her business has been at the expense of others, the initial plans to do a copy of Flamingo Estate, the stealing of the business name from a smaller business, the pretence of being a 'founder'.
If the American 'go-getter' attitude is to trample on everyone and deceive to get where you want to go, then I think she fits that bill for sure.
