9 foot seems reasonable. I believe the tallest man ever was 8.9.
So far i'd vote for a lybrys like axe, an archaic double bitted axe. Battle axes with spikes are usually associated with cavalry or anti-cavalry weapons (to pierce tough armour). Hand and half-sword also should work well.
What type of troop do we have for the Noldor?
We have:
Feanorians
Clad in white and gold
Guardians of the seven Gates of Gondolin
Gate of Wood
Gate of Stone
- coat of arms: robed in gray
Gate of Bronze
Gate of Writhen Iron
Gate of Silver
Gate of Gold
Gate of Steel
The twelve Houses of Gondolin
House of the King
- red-white and golden Banner
- coat of Arms:moon, sun and the scarl.et-heart
House of the Wing
House of the Mole
House of the Swallow
- coat of arms: sign of the Arrow-head; white, purple, dark blue and black colors
- helmets with fans of feathers
- Elven Bows
House of the Heavenly Arch
House of the Pillar
House of the Tower of Snow
House of the Tree
House of the Golden Flower
- coat of arms: a rayed sun upon their shields
- weapons covered with gold
House of the Fountain
- Mail applied with crystal and Silver
- very bright and pale Long swords
- marched into battle to the playing of flutes
- see guards of the seventh Gate of Gondolin
House of the Harp
- coat of arms: A harp of silver shone in their blazonry upon a field of black
- clothes with tassel of gold and silver
House of the Hammer of Wrath
- coat of arms: the Stricken Anvil, and a hammer that smiteth sparks about it was set on their shields
- great War hammers
- large shields
so far I'd say no bucklers for the Noldor. Great Teardrop shields for infantry and roundshields for cavalry and spatha-like swords for infantry and estoc-like seords for cavalry, maybe plus falchions.
Ok, so some points on this:
The weapons and armor brought over by Feanor's, and Fingolfin's contingents should not look the same as the weapons and armor their various peoples have by the time of the Battle of Unnumbered Tears. It's a period of a few hundred years, and I find it highly doubtful that our Noldor will not learn from their first battle experiences. Also, Morgoth would learn from his encounters from the Noldor and make improvements to the equipment of his minions. Then, the elves would learn from those improvements and make improvements of their own. So let's take this a step at a time.
Earlier, there had been a desire to make the sword with which Feanor threatens Fingolfin a xiphos-style sword.
It's a relatively simple design, but good for both cutting and thrusting, and light enough to be considered a side-arm one might carry even when not going into battle. It's also an attractive design, with it's gentle curves along the blade. Of course, this is not a primary weapon, but a secondary one, so I took it a step further and suggested that the Feanorian contingent should have a core of heavy infantry, not unlike the hoplites of ancient Greece.
Of course, I should like to see different armor being used here. I do not remember if Tolkien describes them with conical helms at this point, but if he does, we should use that. Armor is a difficult topic in Middle-Earth. Tolkien almost exclusively puts his characters in "mail" of some kind, and has chain mail being a dwarvish innovation in Beleriand. Either way, Valinorean elves do not have access to chain mail. I do feel that by the end of the first age, having only chain mail, and then for the whole of the second and third ages, having no one come up with anything better makes me a bit incredulous. Also, chain mail was available as early as the Roman empire around 300 BC, became the dominant armor type in Europe somewhere around the 5th century AD, and was starting to get plate elements added to it
Speaking of the Romans, they seem to have been the few cultures to use scale mail effectively, and I do suggest their designs of the lorica squamata as the basis for early elvish armor.
They would also have skirmishers (probably lighter infantry that had not been at Formenos) with spears or javelins, as well as bowmen.
Fingolfin's contingent would be more lightly armed and mobile, especially once they reach Beleriand. I think that New Kingdom Egyptian armies might be a good model for this, sans chariots. They Egyptians utilized many different weaponsets, but what I am recommended is a light scale armor, wicker + hide shields, and either light swords or spears.
When they arrive, the Sindar are mostly lightly armed militia with a small core force of heavily armed soldiers who have the bulk of the dwarf-made metal weapons and armor. Their armor will, as described in the text, be chain-mail. For some reason, these guys remind me of the Persian Immortals, an elite force of archers/spearmen if contemporary art is any indication. While I object to the PJ indication of all elves as convertible infantry/archers, I think we can safely give that status to the elite soldiers of Doriath.
As to Sindarin militia, I think we would likely see a lot of cloth armor (more effective than a lot of people think), as well as light spears or bows.
Now, if we find these suggestions acceptable, we can start asking what innovations we can give the orcs leading up to the Battle of Sudden Flame.
