Neither are actually pure combat units. They're there, but their main functions are either repair, or consumption of materials (Apocalypse, various other bits) though I suppose you might infer that scarabs are a combat unit, they're also mentioned as 'purifying' and consuming things, and acting as recon drones. If we wanted to judge them like that; well, Tau shield and medical drones have no ranged weapons either...
Sometimes the necron lord too,
Only if you upgrade them with warscythes; besides, I question whether canonically their warscythes lack the shooty ability of other warscythes; it seems far more like a balance issue, given that everything else with the glowy green stuff is a weapon, or part of a weapons system
and then there are the C'tans.
The C'tan both have ranged abilities. Indeed, the Deciever is just about the best unit in the game at avoiding close combat, when he wants to.

Okay. Lightsabre, vs Arquebus. Both start out unignited, their users in a feisable melee distance. You exxaggeate; it's entirely possible to envision a close combat weapon that's more powerful than many guns.
They also thought it would be a good idea to put axe blades on the ends of their gauss flayers. Go figure.
The same reason they think it's a good idea to have skeletal looking chestplates. Looking intimidating or cool is a part of their design policy, even though some elements of them are clearly not functional. It seems to work for them. You can see just how much play those axes get in the necrons vs ultramarines picture in the 5th edition book. Where necron warriors show no sign of using them, despite their enemy being in hand to hand with them. In fact, I've seen them swing those axes in precisely one art piece. And even then, there's not actual target in sight, so for all we know, they're really used as a sort of bipod.
You mention the Wraiths, but they could be just as if not more effective if they were equipped with gauss flayers...
Not really. They're only vulnerable when they're hitting something - it's generally literally impossible to shoot a wraith unless he's stabbing yourself or one of your friends. It's possible that a phase shifted gauss flayer does nothing to solid matter, or that phase shifting requires a lot of power, which might prevent a flayer being fitted.
What
would be better, is a solid projectile weapon; when bullets leave the phase field they become normal (inquisitor). But for whatever reason, they don't do that, but then, we know they're keeping a lot of things 'in reserve' rather than deploying every wicked invention they're capable of. Wraiths are a perfectly adequate concept, in the background, for what they're meant to do.
Ethereals have no place in their combat doctrine.
Bollocks. If it habitually goes into battle deliberately, it's an accepted part of their combat tactics. Albeit a stupid one.
Kroot are more useful as an infiltrated firebase than as a melee unit, and Ethereals are flat out useless as anything besides a motivator for the Tau troops. Either are more capable than the rest of the army in close combat, but neither specialize in it.
They suck at it for two reasons;
1. Physiological limitations.
2. They don't train in it, because they have determined that its a lousy way to fight a war when you have easy access to much more destructive weapons that don't require you to approach to within spitting distance to be useful.
We've seen a space marine run up to a crisis suit, while it's shooting and hitting him, and kill it with a sword. "Much more destructive" is in fact, a tabletop convention; their guns aren't really that effective at penetrating enemy forces' heavy infantry armour at all.
