Just what is the best theoretical BMI you should be for a 5k. If there isn't an exact BMI, is there a chart that shows the best weight based on your height?
Googling the question just brings me to casual forums where people pretend weight is a taboo question and don't really answer it.
Obviously the answer depends slightly on the person, but there has to be a theoretical best case scenario.

Your test case scenario is look up the heights and weights of the best 5k runners. Look it up for different ethnicities as well. And know that the lean body type comes from training not starving yourself.
I'd say it's scraping the bottom of the lower range of "normal" based on the CDC BMI calculator. Of course, like you say, it depends on the person. But it also depends on the circumstance. Say I tell you that the best case scenario is a BMI of 18.9, which is 132 lbs for a 5'10" male. When is that weight measured? Take the runner's weight during a heavy training period immediately following a 2 hour summer run in which he took in no calories or water, then take his weight during a light training period after a couple days off and immediately following a large meal. You're going to get two drastically different numbers. So obviously it's a range not just for everyone, but for each individual. Now I could go on and on about how to find your right weight but I'm guessing your question is more hypothetical than looking for advice.
approximately 19 - 20. closer to 19 if you are tall, closer to 20 if you are short.
sprinters are closer to 23.
let´s also take the body fat percentage into consideration.
