Is stringing important with optimizers?

Here is my layout, except the installer says they cannot fit all of the panels shown on the south side so they will move one to the east side.


What is the best string for the east and west panels? I think without optimizer, the correct approach is to string 12 in the south together and then two strings of six each from the east and west and then connect those in parallel together. Does that matter with the optimizes? I tried asking the installer what they plan to do but he was not able to explain it very well.

No. It really doesn't matter with optimizers. If anything you would want to split up your panels in a way that power is divided as much as possible in any given time but the benefit is so small IMHO it's not even worth considering. That's the benefit of optimizers. <6kW/string... end of design considerations.
