Disregard the prior builds, if you want to go full powergaming goodness with Polearm, here's how you do it.
For your ASIs, in order, you take Polearm Mastery, GWM, then Sentinel. Only after that do you boost STR.
For class, go BM Fighter. Get Trip, Menacing, and Precision strike as your first 3. Add Pushing and Disarming after that.
Use the Opp Attack from Polearm to lock enemies 10ft away from you with Sentinel. That's one enemy turn removed. Use a Trip attack on that Opp Attack to knock the target prone. Sentinel prevents them from standing back up, so you just granted everyone advantage for an entire turn.
Use GWM on almost all your strikes, and use Precision attacks to make up for the lack of boosting STR. Combined with advantage from Trip attacks you'll hit reliably.
Take 1 level of War Cleric to pick up Bless + Divine Favor, if your party doesn't have a Bless bot yet. You aren't concentrating on anything anyways, so might as well use Bless to make those GWM strikes hit even more reliably. Use Divine Favor when you don't need Bless to really boost your damage, because you'll be getting 4 attacks per round almost all the time (2 from Extra Attack, 1 Bonus, 1 Reaction (Sentinel or PAM triggering) and don't want to be using your Bonus action to shift Hex around or whatever.
If/after you get to level 11 Fighter, there isn't much else there for you. Maybe another level for an ASI, but meh. For true power gaming goodness, dip 3 levels into Barbarian and take the Bear Totem. Congrats, you can now generate advantage at will (GWM for daaaaays), are basically an uber tank, and get to add even more Rage damage to each of those now 5 attacks per round. Switch between Cleric buffs and Raging depending on the need.
Most of this has already been talked about and discussed...
The cleric thing is new to the thread but honestly not that exciting, 1d4 to hit is meh at best :/ it also means you need wis to be good(or at least 13)
The barbarian thing is a good choice, and one I've done. Not being able to use Heavy armor is pretty rough. I'm still trying to figure out how to remedy this for my character. You need at least a 14 in dex to get close to the same ac, a 16 and another feat to get to the same ac.
What you put together is great for dps, the issue is that you will go down, a lot. Unless you just have godlike stats you can't have a great str, ok-good dex, great con, ok int/cha and a good-great wis. 4-good-great stats is pretty unreasonable.
Also after level 11 there is plenty in fighter, 2 action surges and more dice is great for battlemaster.
