Aghurlal's style with a polearm is predominantly focussed on mitigation. Which is quite different than the FFXIV Lancer Guild-advocated style of "full fearless offense", but it suits him well as a character.
He likes disarming people. He likes redirecting attacks away from himself and taking advantage of the openings left as a result, possibly with his knife if it's close enough quarters. He likes snipping people's vital spots with the sharp end and watching them tire themselves out on the injury. He likes coating the tip of his lance in poison or other drugs that could turn the tide of battle in his favour. He loves distracting people by being annoying so his friend can get behind them and give them a proper stabbing (especially folks the rogues' guild gave him the word to attack, since they're usually pretty bad people).
He doesn't have a dragoon soulstone (and won't for the forseeable future; he hasn't got the contacts or prestige to earn one with), but he has a moderate competence in acrobatics - that tail isn't there for show, after all. So think "passably similar to dragoon moves, but within the range of normal human ability", I guess.
He's fairly proficient in other weapons. If he was disarmed, and the only other weapon available to him was a sword or somesuch, he wouldn't be helpless. But he wouldn't be as good as someone who favours the weapon in question, and the polearm remains by far his favourite to work with for extended amounts of time. His best secondary weapon is shortblades, on account of they accompany a polearm well - in a position where one is too short/long reach to be used effectively, the other fills the gap nicely.
Last but not least, he has the potential to be good with arcanima if he found a teacher and put the hours in, but he hasn't has the opportunity to learn any yet - the fact he's not literate in Eorzean not really helping matters.
