As you say, there's likely no problem with using a regular wall with wooden studs and drywall. You might want to have a 10mm plastic spacer between the outer wall and the first stud so it doesn't "wick" moisture, and keeping the drywall 5-10mm away probably won't hurt either so you can apply a flexible sealant there.
An alternative is to use metal studs and fermacell boards to minimize organic material that might start to smell if it gets damp. However, as mentioned, you may not have this issue, but it might still be worth considering this solution.
Fermacell boards have better properties than drywall when it comes to sound, fire, and fastenings. So, if you plan to use drywall/plywood in the wall, generally one layer of fermacell is sufficient.
