Use same tol defaul values

[jcao-bdai]

Update the default values for tol(lerance) across the board, with the following justifications:

• Using the same default value should help set user expectations, particularly when combined with updated docstrings;
• If these changes break any code, it might help push the user to review previous assumptions of numerical tolerances in the context of the actual use case.
