4) Solution convergence will be highly dependent on mesh quality. Hence, I would recommend you work on the mesh and achieve at least minimum orthogonal quality > 0.1 before your bring your model to Fluent solution. Also, as mentioned in 2), you should use the density-based solver with a good quality mesh to ensure you resolve your flow accurately in this regime.
