Info found for you:
Warriors need to take into account a number of things. Some armours only fit some sizes of races. As you increase in level this becomes less of an importance, but it is something to
be aware of. Also keep in mind that as a Warrior you have no spells. So races with poor night-vision (Barbarians, Humans) might want to be avoided if you are a first time player who does not know your way around the world too well.
Out of the possible races for warriors, Halfling's level slightly faster than other races. Barbarians and Vah Shir level slightly slower, Trolls and Ogres significantly slower, and Iksars slower still.
Some of the high level throwing weapons can only be used by Barbarians, Vah Shir, Trolls and Ogres who also have the highest base strength.
Iksars heal faster and get a natual AC bonus, but they cannot wear most plate armours. Trolls also have a natural healing boost, but are hated in most places. Ogres are also disliked in many towns and even though they do not get a health recovery bonus, they get a lot more hitpoints from their higher stamina, and cannot be stunned when attacked from the front. All of the large races also have the ability to slam. Ogres make a very powerful warrior however there size and experience penalty can be a burden at times.
Vah Shir get a natural safe-fall ability which helps warriors in zones like Velektors Labyrinth where heavy damage can be sustained from a drop. They also get natural infravision. Frogloks get excellent night vision and start with a high skill in swimming.
That should help you decide.
