Actually, I'm not sure if Maxima has a different function for the
negapolygamma (of order -2 in my case), so I just assumed I could use
the balanced polygamma function bfpsi in Maxima.

Several things are wrong here. 2n should be written 2*n. And based on

the image, I think bfpsi(-2,x+1,16) is not what you want. I think the

image says 1/psi(x+1)^2.

In any case, I suspect maxima can't do the limit because maxima can't

figure out what the integral looks like.
