Sounds to me like it changed pitch when the transmission shifted ... Exhaust leak.

It quiets down a lot after warming up. Also don't hear it in reverse.

Definitely gonna have them check driveshaft, axles, Angle gear. I'm really curious to find out where it's coming from.

I looked up what an exhaust leak is, however, the turbo seems to be in decent shape. No weird smells coming from the engine or climate vents

Nevermind. Read more into the exhaust leak and it sounds quiet viable

Exhaust manifold heats and expands sealing the leak.
Exhaust manifold gasket or a loose Exhaust manifold bolt.

The noise is speed-sensitive, not RPM. Something is loose in the drivetrain AFTER transmission.

If that where the case it would not go away after the engine warmed up.

Propeller shaft gets pretty heated by exhaust in front.
