Hello!

I've just started renovating the ground floor of the 1969 split-level home.

In the living room (which will be the first room to be renovated), all the exterior walls are made of lecablock with a brick facade outside. Two of the three exterior walls in this room are completely above ground, and my plan is to frame with metal studs, insulation in between, then drywall on the outside (perhaps also OSB under the drywall). Is this a good idea and approach for the inside of these exterior walls?

The exterior wall that is partially below ground will be plastered and then painted.

The interior walls are currently made of brick, and my plan for them is to glue drywall with gypsum adhesive, spackle, and then paint. Is this a good idea/approach for the interior walls?
 
Yes, but what type of insulation?
And if you choose glass wool or stone wool, you need a moisture barrier behind the drywall.

Yes, exactly, some form of mineral wool was the idea. Ok, so a vapor barrier before you install OSB and drywall?
 
Yep

Install a vapor barrier regardless of the choice of insulation; it is even more important if you choose an organic insulation material, some eco-wool, etc.

This applies to walls above ground.
Below ground, a different approach is needed, as the wall never dries outwards in the construction. Below ground, it's a good idea to just plaster and paint with completely vapor-open paint, silicate paint is commonly used.
The only downside is less insulation then.
Good drainage in good condition is also beneficial.
