Not unless you know that there would be a large adition in the future and you will get the job for service upgrade.

You might be able to charge more. the POCO may well put in a transformer that will be sized at 125A or so no matter what size meter you put in.

The loads for a dwelling aren't really considered to be continuous so you would use a 400 amp service as the minimum size. You could oversize the service/feeder conductor if you so choose but it would cost more.

NEC load calcs for a single family dwelling are already oversized. Going bigger could benifit the EC's bank account or the customer's ego.

400A is good
400A is good
It's true, there are no real benefits to oversizing that residential panel to 600A unless you see a future expansion. Plus, the formulas in the code already have allowed a good size increase on the sizing of the panel anyhow. 400A would be very adequate.
