I found The Language Hoax by John McWhorter pretty good (even though I don't like him otherwise): It's quite readable and very brief. despite its brevity, it discusses most (all?) of the cases that are typically thrown around when discussing linguistic relativity, and he's not dismissive of that kind of research, but shows critical appreciation for the sometimes very convoluted/ingenious study designs
