The aspect the natal Sun and Moon make is crucial. It shows how well your ego (Sun) and emotions (Moon) work together. In a conjunction (less than 10 degrees apart), you're usually someone who has no problem showing their emotional state, and sometimes you can be almost too emotional. In a sextile (60 degrees) or trine (120 degrees), your Sun and Moon work well together, understanding one another well.
In a square (90 degrees), opposition (180 degrees), semisquare (45 degrees), sesquiquadrate (135 degrees), and quincunx (150 degrees), the planets don't work together as well, and there's usually internal conflict for the person since they're usually at war with themselves inside. A semisextile (30 degrees) tends to be mostly beneficial, but you'll need to learn to adapt to situations or suffer from vacillation.
In the lesser-known aspects, quintiles (18 degrees, 36 degrees, 72 degrees, 108 degrees, 144 degrees) tend to show you present yourself best creatively. Septiles (51 degrees, 102 degrees, 154 degrees) have a little more friction, so they can show how you are inspired. Noviles (40 degrees, 80 degrees, 160 degrees) tend to be positive, light, but needing some more courage. Undecims/undeciles (32 degrees, 65 degrees, 98 degrees, 130 degrees, 163 degrees) tend to show someone who engages in fantasy, is socially conscious, and feels there's something missing.
A squine (105 degrees) is halfway between a square and a trine, and shows someone who lets blocks lead to laziness or laziness lead to blocks and holds themselves back. A quindecile (165 degrees) shows someone who is incredibly disruptive to themselves (I'll have more on the quindecile and one of the undecims in a future post).
If you have your Sun and Moon at difficult aspect to one another, that doesn't mean you're screwed for life. You can use midpoints to help rectify any difficult aspect between two planets. A midpoint is literally the exact middle of two points. In astrology, it shows how you can mesh the energy of those two points together to get them working harmoniously. If you have your Sun and Moon at difficult aspect, just check out your Sun-Moon midpoint (you can get that at astro.com). The sign it's in, the house it falls in, and any planets on it will help you to see how you can make the best of a difficult aspect.
