A map always has unique key values. Where you have multiple objects that could share the same key, you must make the map's values allow for this. For example, here I would make your Map<string,object> FinalMap actually Map<string,List<Object>> finalMap. Now you would populate it thus:
for (Object obj : arr) {
List<Object> entries ...

Map<String, Object> fieldMapLevel_0 = (Map<String, Object>)fieldMap.get('Accts');
The value of the key Accts in your JSON is a List, not a Map:
String jsonPayLoad = '{"Accts":[{"Name":"ABC","Exp":25,"Languages":[{"Name":"Apex","version": []},{"Name":&...

If I have two Map<String, List<Object>> maps and I want to merge them, I can't just use:
Map<String, List<Object>> x = ...;
Map<String, List<Object>> y = ...;
Map<String, List<Object>> z = new Map<String, List<Object>>();
z.putAll(x);
z.putAll(y);
This won't merge lists from x with lists from y ...

If you always use the same (partial match) criteria for finding values (here you match the Text value), the best solution is to actually use a Map not a List. Something like this:
public class SelectItem {
public String Text { get; set; }
public String Value { get; set; }
}
public void FooMethod() {
Map<String, SelectItem> items = new Map&...

The arrow functions don't exist in Apex. This is plain JavaScript.
You can conceptually find an element if you already have it:
SelectOption[] options =
new SelectOption[] {
new SelectOption('a','a'),
new SelectOption('b','b')
};
SelectOption target = new SelectOption('b','b');
System.assertEquals(1, options.indexOf(target));
This operation is ...
