Here is a book that puts a serious knock on the Mesoamerican theory.
Joseph Smith at one time, posited that the original landings happened near Valparaiso, Chile. The book about BoM ecology supports this idea.
I've always liked a South American location for the majority of events in the BoM.
As an aside, Murdock-Morris https://www.mmetours.com/ travel agency provides many LDS oriented tours to "BoM" lands as well as Israel etc. This agency is not affiliated with the church although it has its origins as BYU travel.
Another aside is that the Darien isthmus is basically not passable, even to this day. Much more that 24 hours if even possible. There is a reason that the Pan American Highway, built during WW2, skips this part! Not buildable either.
