It appears that gr.message_sink and gr.msg_queues are for digital data.
but my flowgraph (periodogram) is for analog samples,
complex baseband samples from usrp --> stream to vector (vectors of
fft_size) --> FFT
Â --> complex to mag squaredÂ --> (sink or block to be determined)
Is their no choice other than file sink?

You can use a file sink to write the samples out to a file, and write
some program to process the file.
Or, you need to create your own block in c++ or python. If c++, the “how
to write a block example” is a good reference. If python, the wxgui
sinks are a good reference (see gr.message_sink and gr.msg_queues to get
data out of the stream and into
