You may want to look into one of the insulated basement finishing

Thanks. *If I decide to do the exterior walls, I will probably just build a

Masonry walls are not waterproof. Any water vapor or water intrusion,
from either side of the wall, will make those studs a lovely growth
medium for mold and promote rot.

If you are set on the wood studs they should be treated and other
steps should be taken to make your time, effort and money last as long
as possible. Otherwise you'll be shooting yourself in the foot if
you're going to be in the house for a long time, and if you won't be
you'll be creating a problem for the next owner.

Always take care of the next guy. Half the time you are the next guy.
