Does anyone know of anything more granular - preferable with the ability
to capture the data and insert it into a spreadsheet? Sounds maybe like
a Raspberry Pi application?

does it on a Pi, and will sell you the parts need to hook up to your meter
for not-very-much.

all you need is a current sensor and some A to D for the Pi. Then you
can build yer own

If I were to have a smart meter fitted (which I've hitherto resisted!)
but to stay on a fixed tariff, could this be made to provide me with the
required data?

Yes:
