2019 Lexus GS — light-throttle shudder around 35–45 mph

2019 Lexus GS 350, about 13,000 miles. There is a rumble-strip-like shudder at steady light throttle in a narrow speed range. Harder acceleration or lifting off makes it disappear. How would you separate converter behavior from engine misfire or wheel/tire vibration? I am trying to get the facts straight before spending money.

Before you spend money, owner data points help more than a generic forum diagnosis on a 2019 Lexus GS.
