You’ve already done many large regional reconquests and crusade-style runs (King of Jerusalem, The Last Crusade, Mare Nostrum, Baltic Crusader), so focusing on Balkan dominance as Serbia (Lazarus) and Iberian reconquest as Granada (The Re-Reconquista) plus a related crusader/Crusader-state play from Provence to form Jerusalem (Good King René) build on your proven strengths with achievable, thematically linked goals.
