RE: Querying from local data

For example:

a!localVariables(
  local!data:{
    {id:1, lob2:"Commercial Banking", lob3:null ,lob4:null},
    {id:2, lob2:"Commercial Banking", lob3:"Commercial Banking", lob4:null},
    {id:3, lob2:"Commercial Banking", lob3:"Commercial Banking", lob4:"CMB"},
    {id:4, lob2:"Commercial Banking", lob3:"Commercial Banking", lob4:"GPB"},
    {id:5, lob2:"Commercial Banking", lob3:"Commercial Banking", lob4:"RBWM"},
    {id:6, lob2:"Commercial Banking", lob3:"Commercial Banking", lob4:"HOST"}
  },

  local!selectedLOB2: "Commercial Banking",
  local!selectedLOB3: "Commercial Banking",
  local!selectedLOB4: "GPB",

  local!lob2Indices: wherecontains(local!selectedLOB2, touniformstring(index(local!data,"lob2",null))),
  local!lob3Indices: wherecontains(local!selectedLOB3, touniformstring(index(local!data,"lob3",null))),
  local!lob4Indices: wherecontains(local!selectedLOB4, touniformstring(index(local!data,"lob4",null))),
  
  /* have to do a nested intersection here since intersection() only accepts 2 arrays */
  local!matchAllIndices: intersection(
    local!lob2Indices,
    intersection(
      local!lob3Indices,
      local!lob4Indices
    )
  ),
  
  local!id: index(
    local!data.id,
    local!matchAllIndices
  ),
  
  local!id
)

Your index() call ends up passing in all members of the array multiple times - the whole set, then all the lob3 matches, then the one lob4 match. What you should be doing is getting the indices (if necessary) using your whereContains lines, and then finding the items in the original array that match all 3 (though it seems you could just look up the position of the match in lob4, with the current data set anyway).
