An Arista 7280SR3AK-48YC8 has the port selection you want along with FIB 
scale.  IDK exactly what you mean by meaningful packet buffers, but it's 
not a dedicated small-buffer edge box.  It should run about 300W.

The older 7280SR2K-48C6 also has the port selection and FIB scale you 
want and can be found used at a price that may be more budget-friendly 
but is near or just past end-of-support.

The non-K versions will do 2M with (what seems like) realistic FIB 
compression at DFZ-scale but are limited to more like 1M in hardware 
which may not be what you're looking for.  Arista claims 4M+ routes on 
the K versions with that same FIB compression and IIRC 2M or so in 
hardware depending on partitioning.
