F-1 paper should produce a lower contrast than the higher
number
papers. D-19 is a higher contrast developer. D-72 or
Dektol might be
better choices than D1-19.

Fog might be from paper age or history of how it was stored.
It also
might be from a safelight or other light leaks in a
darkroom.
I have some pretty old Kodabromide and do not see fog.

I doubt if there is much difference in contrast between
D-19 and Dektol. For one thing both are quite active and
also paper is developed to "completion" meaning to about the
highest contrast its capable of. This is unlike film which
is usually developed to a much lower contrast than its
maximum.
All papers can become foggy with age and Kodabromide
was discontinued quite some time ago. Additional bromide
will help with fog but benzotriazole is more effective and
does not lower the speed quite as much.
