Best Grappling Build?

Me and my buddies started a PF2E game recently and my DM (long time friend) has expressed his willingness to homebrew some actions and such to make a pure grappling build viable (especially with me being the only frontline right now). But I’m curious about what the best rules as written grapple build is. So far I’m a level 2 jotunborn, with jotun wrestling, barbarian with the ape animal instinct, and the wrestling dedication through the free archetype optional rule. I’m going to be taking all of the wrestling moves through my free archetype but is there better levels to take certain options? Cool interactions that aren’t super obvious? Second archetypes I should look into? I wanna feel like King/Armor King from tekken lol.
