2 weeks day, 2 weeks night, how would the sleeping pattern of the planet's dominant species work with a 28 'day' Day?

Okay, so I have this binary planet system. The main planet a bit bigger than earth with a size appropriate moon-planet. Both are habitable and with a humanoid species that evolved there.

But, I know that the rotations of the planet are tidally locked as a result and a 'day' on the moon planet is much longer than the primary planet, about 27-29 days in earth days and a much heavier tide on both sides

On both planets, the natives are humanoid enough; requiring almost all basic things we do; oxygen, food, water, sleep etc... and a lot of vegetation"” and accompanying wildlife (predator & prey).

Question:

Since the days are vastly longer on the moon-planet, how would that effect the wildlife and natives?

I'd assume 2 weeks in day and 2 weeks in night; if that's the case then It could make things easier to see.

Vegetation life would be good, the 2 weeks or so, the plant life would develop bio-luminescence (using the energy absorbed in the 2 weeks with sun) to keep itself alive.

But my primary focus is on the humanoids.

Would hibernation for 2 weeks be the more obvious choice for their physical wellbeing to deal with the long days. (I am aware humans cannot hibernate but other mammals do)

Or would they have to live 2 weeks in darkness and 2 weeks in light and use our sleeping pattern of 8 hours a sleep in a designated amount of time?
