LED wall that fits

Under a 9.8 m ceiling with 1.5 m trim and 0.3 m clearance you get 15 rows of 500 mm tile flown. Along the 66.4 m wall a Absen PL2.5 Plus V2 wall runs 106 x 15 (21200 x 3000 px, 12,402 kg, 254.4 kW).

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.
