Mauler
Pathfinder 2nd
The Mauler is one of the many generic archetypes introduced in the Advance Player's Guide, available to almost anyone with sufficient strength. In particular, the entry feat gives you proficiency with two-handed weapons and the rest of it focuses around these sorts of weapons (including co-opting some feats from Fighter).
In particular, this gives you plenty of ways to use combat maneuvers using big weapons, shoving enemies around and knocking them down.
