The best person to ask would be the electrical inspecter that is coming out to approve the installation....
What Im trying to say is say you pulled regular wire through conduit, this would be unacceptable for an installation that is wet... direct burial.. pools.. etc, because the conduit is considered a wet location.. piping leaks this is why. Liquid tight is continuos armored and coated so it is impervious to leaks. The only thing conduit is used for is mechanical protection. So back to my example, I put conduit in ground, I need to still pull water proof cable in the conduit.
Ill try to illistrate as best I can on phone.

If you are staying in a wall or fixture you do not need conduit, as this is considered the mechanical protection.
If you get a good inspector they will help you... I belive you didnt pull permits for your build based on your progression pictures.
Typically the progression goes like this...
Permit -> Build Wiring, boxes, conduit. No drywall or coverings. -> First inspection. Inspector will tell you what is not acceptable and things to change. -> Fix messups -> finish building -> hopefully final inspection, if there are some minor messups left they might pass you and write the things you have to fix on the sticker -> enjoy.
My warning to you and others that do not get inspections... if your house burns down, even if its not electrical related, they will pin it on the wiring and not pay... maybe.
@Brew12 is a good resource.
This is a long post on phone haha.
