In the beginning you fight a lot of cultists of Baphomet, whose favored weapon is the glaive.

Lore wise it's on point.

Every weapon type has at least worthwhile if not more basically at every 'power level'. Plus, the intelligent weapon you get early can be turned into any weapon so, at minimum, your main character should have a favored weapon covered. But, yeah, lots of glaives. But, hey, usually it is (long) swords so at least it is different. L0L

Companions, especially early on are not a very diverse as a lot a focused on ranged (longbow). Also, Wenduag is a fighter and can use glaives. I would have liked if she was actually more focused on melee combat though.

BTW Those longswords in Baldurs Gate still haunt me sometimes.

She has the stats for any fighter style, you just have to level her up manually.
