[sdiy] Matched Transistor Specs

I've been looking at dual transistors for exponential circuits. If I'm
okay with surface mount, there seems to be a bewilderingly large number
of parts available.

Besides the maximum voltage/current ratings, what should someone look
for in a good exponential converter pair? Do any of the typically
published specs like Vceo, Is, beta, etc matter much in this use case?
