Amplifi has both "band steering" and "router steering" options that you can configure on the routers. Band Steering will cause the routers and access points to kick you off 5Ghz faster, if 2.4Ghz would give you stronger signal, and vice-versa. Router Steering will cause the routers and access points to kick you off the one you are attached to more quickly, and thus cause you to re-associate with the network on a router or access point that is closer to you and would give you a stronger signal. I can't speak for any other vendors, but that's the kind of thing I think you're looking for.
