You could use your jigsaw if you break the end off a blade so that at

full stroke it is just long enough to reach through the floorboard.
Then
you should be able to jigsaw along the centre line of the joist
without
actually cutting the joist (much!).

Thanks for your reply. What method or technique is best to break the
end of the blade?

(your circular saw will also do the job since you can set the depth
of
cut on that to the thickness of the boards)
