I'd probably argue that, barring specific requirements that these might not cover, the NXP i.MX6/7/8 would probably be my default for something like this in volume. ~Motorola~/~Freescale~/NXP have been incredibly great stewards of the platform and provide significant lifetime guarantees for their parts (like 10+ years often). Plus you can generally run mainline kernels on them unless you're doing something special that requires something from their vendor branch.
