You've been asking about this on several different forums and in several different threads. I think we've given you a pretty solid idea of what you can do with a level 10 Paladin, so at some point you'll just have to decide what your preference is.
Personally, I wouldn't do a Polearm build with anything other than a Variant Human, and if you're doing a hard stop at 10 I don't think I'd even attempt a Polearm build. Gladius Legius spelled out how you would do one though:
Level 1: PAM
Level 4: GWM (or +2 STR if there's nobody who can cast Bless or give you a reliable form of advantage)
Level 8: Resilient (CON)
Haste is a huge part of this build, so you really need Resilient (CON) at level 8.
Sorry about spamming this topic on multiple forums, I did cause I like to have as much opinioms as possible. I think 3 feats might be a lot for lvl10 cap.
