Hoping to learn an Indigenous language native to my area

The region I live in, Niagara, doesn't have any reserves, but there are two just near Hamilton. One is primarily of the Haudenosaunee peoples, whereas the other is of the Mississaugas, who are an Anishinaabeg people.

In both Canada and the US, Kanien'keha (Mohawk) has become the dominant Indigenous language spoken by the Huadenosaunee, whereas for the Mississaugas it is Anishinaabemowin.

The question I have is, given the history of these groups in the Niagara region, does it make more sense to learn Kanien'keha or Anishinaabemowin?
