I'm looking for:
• Has at least 6x 100G ports
• Has a smattering of 10G/25G ports

better
• Has reasonably low power usage, I don't need 1 kw going to a router
• Is cost-effective
• Used is fine
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.
