ISFJ and ESFJ
ISFJ remembers the practical thing that makes someone comfortable, and gives it quietly. ESFJ hosts the actual day, not the idea of it, and is the person people know to ask. You will run a household, a team, or a weekend better than either of you runs it alone, and you will both forget to count your own effort unless someone makes a rule about it.
ISFJ is allowed to say when the quiet giving is too much. ESFJ tracks the mood of the room and has to let someone track theirs. If both of you spend the day on everyone else, the evening becomes a contest about who noticed more, which is the opposite of what either of you meant.
Split the hosting. ESFJ can be the person the room can see. ISFJ can be the person who already handled the gap before it was a crisis. Then swap, once, so the quiet work is seen and the visible work is allowed to sit down. Care that is only implied will be missed by the one person in the room who is also busy caring.
