Cantilever seal and insulate prior to finishing basement

[Eldon62]

This is the situation.
I'm Eldon, a 54 yo Retired Air Force Engineer.
I just bought a house and am starting the process of finishing my basement.
I discovered the following design and need good advice to best fix it.
I've been following Dana and have been impressed with the quality and detail of the information.

Ok, I have a 2 foot cantilever on the front of the house (see pics)
on the exterior it is a soffit with vents attached to joists with staples.
Between the joists is old cellulose kraft faced.
There is no barrier between exterior and interior basement.
Basement is full slab with cinder block foundation walls.

I live in Chattanooga, TN Zone 4A.

Thoughts.

Not clear what you are fixing. Insulation of the basement walls? Replace insulation in soffit? Or waterproof basement block walls? It seems you are asking about better insulating the basement, but not sure at this point.

You'very been replying to me in a conversation.
I'm fixing the airflow problem in the cantilever prior to starting complete basement finish.
