If Normalize makes Thunder Wave a Normal type move, Thunder Wave can affect type Pokemon but not type Pokemon, unless the type Pokemon is holding a Ring Target.
If the move Flying Press is affected by Normalize, it deals Normal type/ type damage. If the move Freeze-Dry is affected by Normalize, its ability to hit type Pokemon super effectively is retained.

Pokemon Mystery Dungeon
In Pokemon Mystery Dungeon: Explorers of Time, Darkness, and Sky, as well as previously mentioned effects, Normalize turns the standard attack into a Normal type move. It also makes throwing items deal Normal type damage. This does not apply to fixed damage items (Geo Pebble, Gravelerock, Unown Stones, or Rare Fossil).
