What is the optimal room size for the highest Friendship Points (FP) value? What are the differences in FP?

What are the differences between FP 8x, 9x, and 100?

I tested it out, and it seems that for the interior of the house, a grid size of 66 or 77 is the most cost-effective.

7*7 = +15 (Theoretically, it should be +14, but the result is +1 extra. It feels like the best value for CP.)

6*6 = +12 (I forgot to mention the exact size)

5*5 = +10 (Average size)

After placing furniture (each adding +2), after reaching 17, each additional item will directly add +3 (up to a maximum of +20).

Is it true that the optimal CP value is achieved with a room size of 7*7?

In my settlement with 28 settlers. I built 7x7 houses (5x5 interior). And this is enough for all settlers to have 100 happiness, but for this you definitely need to install a lot of different furniture and feed the residents only delicious food (if you set up constant food production, this will be easy).
