Type selection usually happens in a still frame. If the brand has any motion at all, that is testing under the wrong conditions.
Check the counters at speed
Tight apertures fill in when type moves quickly or scales fast. Set the candidate at your smallest real size, animate it, and watch the a, e and s.
Check the weight jump
Many families have a gap between Medium and Bold that reads as a flicker in a weight transition. If you plan to animate weight, you need the intermediate.
Check it against your easing
A geometric face with a sharp ease-out looks mechanical in a way that may or may not be what you want. Test the pair, not the parts.
