I need to install about 200 sf of the top-nailed (older style, not the
tong & groove type) red oak hardwood floor.

should I use 18 gauge brad nailer with 1" nail? Or should I go
for a 16 gauge finish nailer with 1" nail?
Thanks in advance,

I don't know if the 16 ga is best, but I do know the 18 ga brad is wrong.
Brads are for tacking things in place, not for long term securing of things
like floors.
