At these low frequencies maybe you don't care. Getting
a good manufacturer's SPICE model that includes the
electrolytic's inductance would let you assess with some
realism. But I doubt inductance matters at 1Hz. Polarity
however might, depending on application (signal, and the
surrounding circuitry - if bias can be positive or negative
then you need a nonpolarized cap, while most of the high
value bulk electrolytics are unipolar (meant for supply
filtering, not a potentially-reversing signal).
A 47uF 10V ceramic is smaller than any electrolytic I've
ever seen, if this matters to you, and will be better in
every electrical & environmental aspect. Cost, maybe
not, but you're still talking not-much.
