I would recommend that you take advantage of the expertise of the staff at your local lawn and garden stores when it comes to picking grass varieties that will do well in the site. There are a number of considerations that will determine the relative success of the turfgrass vs. the clover in your new lawn. Generally, you shouldn't need to worry too much about the clover, although it will be more competitive in shady areas and where moisture is consistent. If your lawn is full sun and unirrigated, the clover will likely need to be re-seeded annually. Read this article from MSU Extension for some more info: https://pollinators.msu.edu/resources/pollinator-planting/pollinator-lawns/
Also, this is a nice article from the University of Maryland Extension that considers the pros and cons of using micro-clover varieties in a bee-friendly lawn: https://extension.umd.edu/hgic/topics/lawns-and-microclover
Yes, the reason that there are no ratios given is because of the difficulty to predict how well the two (turfgrass and clover) will establish and persist together. It sounds like the no mow is thriving in that site, so I would recommend using less grass seed and go heavier on the clover. With time, the two will work out a stable equilibrium.
