Naturally high contrast and small grain? Pan-F is $50+postage for 100 feet of 35mm at B&H. Looks gorgeous in Rodinal.
Fomapan can be contrasty too but it is quite crunchy compared to Ilford offerings in the same speeds, not to mention it's about 2/3 stop slower than advertised in most developers. Think of the Fomapans as requiring a 1-stop push to achieve box speed and they really struggle beyond that point. They mostly get more contrasty without gaining much shadow detail.
