I remember something about tidal pull 'massaging' the planet, which something-something tectonic activity. Then the tectonics stir up nutrients and such for a biosphere.
...I do think size of orbital possibilities might limit opportunities for life, or at least possible types of life. (Our moon is too small for an atmosphere, but I'm not sure if our moon with a hydrosphere could suppourt life...)

It also creates ocean tides, which are valuable for inspiring life.

There are optimum sizes, differences, temperatures, and so on. Anything with liquid water is a prime site for life. But life is extremely inventive and appears in a lot of unexpected places.
