That would be nice for you and me - correct. (Subject of the sentence, the thing that does the verb, in this case “would”, is “That”. It cannot be you and I, because “I” is always a subject pronoun and “I” is not the subject here.
Both “myself and my team” and “me and my team” are very incorrect if you mean them to be the subject, the thing that does the action or verb. The subject pronoun is always “I”. “Me” is an object pronoun. It needs to be “My team and I achieved the goal.” The correct form is always to put “I” last in the list- my team and I. Never I and my team.
If it’s “The boss gave the award to my team and me,” that is correct. The subject here is the boss - the one doing the action, who did the giving - and not I. Again, it has to be “my team and me”, not “me and my team”. Always put yourself last in the list.
“Myself” cannot be used in either example, as it is not a subject or object, direct or indirect, of a sentence. It makes no sense at all. It’s used reflexively - I washed myself - or perhaps for emphasis or clarity - I won the award myself, I myself won the award. But you can’t use myself on its own without “I”. Similarly you can never use “yourself”.
Subject pronouns are - I, you, he, she, it, we, they.
Object pronouns are - me, you, him, her, it, us, them.
