Insert this formula in a custom column

"Proj: " & [Team] & (if [Category] <> "" and [Category] <> null then "| Cat: " & [Category] else "") & (if [Valid] <> "" and [Valid] <> null then "| Valid: " & [Valid] else "") & (if [Owner] <> "" and [Owner] <> null then "| Team Owner: " & [Owner] else "")

Here is a method that can be generalized to various column headers. You could even easily add more columns if necessary for your actual data.

 

Since your data seems to have "space" characters for the blanks when pasted into my Power BI table, I "Trimmed" them away. If they are really nulls or empty strings, you may need to edit the code.

 

I created a translation table from column names to "Append Result" which you can also edit if needed.

 

And I used List.Accumulate to get a list of the valid (non-empty) fields to be concatenated.

 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXIE4sjUYiAZoRSrE61kBGQ5AbECGINEjKE8v3yQUrCQCZDlDBWOUoqNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Team = _t, Category = _t, Valid = _t, Owner = _t]),
    #"Col Names" = Table.ColumnNames(Source),
    #"Changed Type" = Table.TransformColumnTypes(Source, List.Transform(#"Col Names", each {_, type nullable text})),
    
    #"Col Name Translation" = List.Zip({#"Col Names", {"Proj","Cat","Valid","Team Owner"}}),

    #"Trim Spaces" = Table.TransformColumns(#"Changed Type", List.Transform(#"Col Names", each {_, Text.Trim})),
    
    #"Add Column" = Table.AddColumn(#"Trim Spaces", "Append Result", (r)=>
        let 
            #"Records to Concat" = 
                Record.RenameFields(
                    Record.SelectFields(r,
                        List.Accumulate(
                        Record.FieldNames(r),
                        {},
                        (s,c) => if Record.Field(r,c) <> "" then s & {c} else s)), 
                    #"Col Name Translation",
                    MissingField.Ignore),
    
            #"Concat" = List.Transform(
                            List.Zip(
                                {Record.FieldNames(#"Records to Concat"), 
                                 Record.FieldValues(#"Records to Concat")}), 
                            each Text.Combine(_,": "))
        in 
            Text.Combine(#"Concat", " | "), type text)
 in
    #"Add Column"

 

Results from your first four columns of data:
