I need the collective brain trust to help optimize a Hateful Rager for killing Giants
I have never played a regular Barbarian and am entirely unfamiliar with Rage Powers. Can the Greater Beast Totem allow me to pounce with weapons other than the claws?
Feats beyond Power Attack, and Extra Rage, what else is there?
Can the Greater Beast Totem allow me to pounce with weapons other than the claws?
Yep. The nat attack limitation is only for those that get it through that feat path.
Go with the Toothy ART so you begin with a bite attack. Wear a quiver full of arrows. Take Destroyer's Blessing and free-action draw an arrow to sunder as part of your secondary bite attack when you full-attack with your weapon.
Smashing an object:
"Smashing a weapon or shield with a slashing or bludgeoning weapon is accomplished with the sunder combat maneuver. Smashing an object is like sundering a weapon or shield, except that your combat maneuver check is opposed by the object’s AC. Generally, you can smash an object only with a bludgeoning or slashing weapon."
Eating the arrow counts as a sunder maneuver, which only provokes from the target of the maneuver, which is yourself. So you can snack on arrows when threatened without issue.
This solves your lower rage rounds issue.

As a half-orc, I'd capitalize on the human FCB which improves Superstition.
If you're okay with rage cycling then you should follow the path to Eater of Magic, then top off with Strength Surge, Savage Dirty Trick, and Unexpected Strike.

If you're expecting to fight a lot of Giants then I'd take full advantage of that. Dip one level into Reliquarian Occultist for Legacy Weapon and the Luck Domain (see if you can start with 14 wis).
You can hold the charge on Bit of Luck to get the roll every d20 twice effect without wasting a standard action at the start of combat. Prolong it with another round by wearing the Headband of Fortune's Favor.
Then either rush a Keen weapon (that or Bane with Legacy Weapon) or Improved Critical for Faith's Hunter. It's not entirely set in stone what spell abilities affect SLAs, but since this trait doesn't refer to spell levels or casting in any way I'm very confident it will apply.
So whenever you crit a favored enemy, you prolong the "roll every d20 twice" effect by one round. With a 15-20 weapon when rolling twice you have a 51% chance of scoring a critical threat. Per attack.
^---- Do all this stuff that Wonderstell is talking about and plan on Rage Cycling. The best way to Rage Cycle is to get a Flawed Scarlet and Green Cabochon (Ioun Stone) for 8,000gp and then at level 8, pick up the Internal Fortitude Rage Power. Now whenever you get fatigued/exhausted, you become sickened/nauseated instead, and while Raging, you're immune to sickened/nauseate. As a bonus, you get the Endurance Feat from the Ioun Stone as well, so then you can sleep in your armor without being fatigued.
This solves your lower rage rounds issue.
I would never get away with that

Eater of Magic is cool, but the others don't seem that good.

Multiclassing is not really my thing for this build unfortunately
Then either rush a Keen weapon
That is the plan with a Falchion
