Raptoran is an interesting race. No LA with a slowly scaling flight speed. Flight can either make things trivial (flying across a pit) or be a pain in the butt (what do you mean I don't have room for my wingspan? I'm a five foot cube!). Sky domain synergizes well with the race, too. The other racial benefits are ok. A boost to jump checks eventually gets replaced with flight. Pact of the Wind Lords gives a boost your caster level for (air) spells but there are very few spells with the air descriptor. I would be surprised if this ever came up. Unerring Direction is a neat roleplay ability but five ranks in survival gives you the same effect. Lastly, you get footbow as a martial weapon instead of an exotic weapon. But clerics don't get martial weapons so it isn't doing you any favors there. If you want a footbow, you're going to need to burn a feat. But if you're burning a feat, you might as well get longbow since you're more likely to find that as loot or be able to buy one in a city somewhere.
The cleric substitution levels are nice and flavorful but they aren't doing you any favors if you take the Skypledged prestige class. Many of the substitution levels' features overlap with the prestige class. I would probably pass on the substitution levels.
Skypledged is a neat prestige class. The spellpool ability would be handy for dealing with situations where you need a spell but don't want to always have it prepared. Things like curses, poison, or disease. Just be sure to have some downtime to repay your debt to the spellpool. The summons are a nice touch and it's always helpful to have a friend you can call on. If you make it all the way and get Cyclonic Doom, be sure to ask your GM if it affects ranged attacks; if enemy, or your, arrows get blown away. Lastly, I don't know how much the Beckon Winds feature will be useful but, again, really nice and flavorful.
The domain choices for Tuilveil are all ok. Nothing great; nothing awful. Sky Domain is the exception since it synergizes well with Raptoran.
Elf is always a solid pick but you have to be careful with that -2 Con. Elves automatically get longbow proficiency and the elf domain would give you point blank shot for free, too. Pick up Precise Shot at Level 1 and you're an effective archer! Pew pew pew! If you want to be an archer, you're pretty much pushed into this race/deity.
Elf domain does have some nice spells in it, adding variety to the cleric spell list. However, true strike is a bit of a trap. Spend this turn to hit something next turn. Maybe if you're setting up an ambush would that be useful. Sehanine also has Travel and Trickery domains, which are awesome! Repose is basically a non-evil death domain. Moon would be great for fighting werewolves. Knowledge and Oracle are very similar in granted abilities and spell lists. I would pass on Dream Domain, too. Immunity to fear is easy to come by otherwise, especially if you're starting at high(er) level.
What to say about human? Extra feats and skill points are always welcome.
If you're not using level adjustment buy off, I would avoid Aasimar. Giving up caster levels is not always a good idea. The paladin's spell list is going to be very limited. And the sorcerer is going to be limited by spells known. Cleric allows you to be versatile with spell selection. But the question is, do you want to get the next level of spells a level up later?
With that being said, the bump to Wisdom and Charisma works well for cleric. You can cast light once a day but also have darkvision. So that's kind of a moot point. Elemental resistances are nice but you will be able to surpass them quickly enough when you get things like Resist Energy, Mass. One neat thing though is that if go somewhere extremely cold, those resistances will let you avoid making saves vs cold damage from the environment. (See Frostburn!) As a native outsider, you can avoid things like Charm Person but you also can't benefit from things like Enlarge Person. Sadly, I don't think there is an Enlarge Monster spell. So, maybe a slight advantage in your favor.
For Human or Aasimar, I like the Chastity Domain from Selune. The Night domain gives Human some nice bonuses but not so much to the Aasimar. The spell selection on Night Domain is good, too. Lastly, Selune has Travel Domain, which I am a fan of.
All of these are solid options. I think I would break it down like this:
Do I want to fly around? - Raptoran Cleric of Tuilveil (And maybe prestige into Skypledged)
Do I want to be an archer? - Elf cleric of Sehanine
Neither of those? Human Cleric of Selune (Summoner or whatever)
In the end, remember this is YOUR character. Pick what you think is going to be fun and interesting. You don't have to listen to the random ravings of some guy on the internet.
But I really do hope this helped you make a decision.
