What are recommended high and low contrast super 8 film stocks?
Is it just a rule of thumb that low ISO stock is low contrast and visa versa?

No, low ISO means lower sensitivity to light -- it has nothing to do with contrast.

Super-8 color reversal would have more contrast than Super-8 color negative stocks -- that's probably the biggest decision you can make regarding contrast.

Otherwise, in color reversal, a stock like 100D ('85) has a little more contrast than 64T.

I'm not sure any of the special "lower-contrast" negative stocks are sold in Super-8, which would be Fuji Eterna 400T and Kodak Expression 500T ('29).

But Super-8 neg would already have a lot less contrast than Super-8 reversal. Otherwise, the Super-8 neg stocks would match each other fairly closely in terms of contrast -- for example, 50D ('01), 200T ('17), and 500T ('18) all have a similar contrast/color design, they just vary by graininess.

Graininess and speed are related -- higher ISO stocks will have more grain, since they are more sensitive to light.
