I use a Chemex but this question must be valid for all filter drip methods. If you keep the same dose/brew water ratio (in my case, 1:16.6) and reduce the dose and water accordingly from a previous formula, do you tighten the grind and go for the same time as before or just accept a shorter brew time?

With espresso, I would pair a finer grind with less coffee in order to preserve the flow rate. But I don't know if this logic carries over to filter coffee.

I shoot for 4.5 to 5 minutes brew time including a 30-45 second bloom. I wait for the bloom to start to collapse before starting the pour.

I adjust the grind to hit this brew time window.

I set the volume of coffee based on the taste. I find I may need more of one origin than another. I have a starting base weight of 32 grams for my mid sized Chemex (6 cup - 4 US sized cups). I will work up or down from this starting weight based on how the coffee taste (light / strong).

That's just how I do it. I am sure others will have a different methodology.

I do the same as Mick - I tighten the grind, keeping overall brew time constant.
