Hi,
Can you suggest a good type that will fuse with this shape? It is a work in progress visual identity.

Look for incised, inscribed, flared.
Those slightly pointed rectangles remind me of Friz Quadrata.
Magma by Sumner Stone, or Basalt. Maybe Mantika Sans?
I'd be careful about trying to hard to duplicate the weight and forms of your symbol. Could dilute the impact and create a bit of a thud.
There's Requium, which echoes the shapes but would partner the simplicity of your shapes with some elegance.
Or you could go with a type face that more subtly echoes rather than reflects the forms. Something like a Janson Text or Founders Caslon. You'd get the flexed shapes of your form in the serifs of the without a complete duplication.
