Bloodsoaked Ruins is the closest fit on the game's own numbers: Emilie's kit multiplies ATK, and a weapon is ranked here on whether its ascension stat and its passive act on that stat. Calamity Queller, Lithic Spear and Crimson Moon's Semblance come next. No playtested ranking has been imported for Emilie, so this is arithmetic over the kit data rather than a damage measurement.
Run Deepwood Memories on Emilie, with A Day Carved From Rising Winds and Disenchantment in Deep Shadow behind it. Main stats are ATK% sands, Dendro DMG Bonus goblet, CRIT Rate / CRIT DMG circlet. Roll substats in the order CRIT Rate > CRIT DMG > ATK% > Energy Recharge.
Talent priority is Normal Attack > Elemental Skill > Elemental Burst. The Elemental Burst costs 50 energy, which is what an Energy Recharge target has to clear.
The strongest team is Alhaitham, Emilie, Xiangling and Bennett, built around Emilie: Dendro · Burning.
