I’d run 3 of the big boards 288 or 304 diodes
Maybe a hlg320 to run all 3 at approx 100w per board.
Edit: didn’t see the why...
Your only covering 9sqft so 320/9 should put u in the 35-40watt per sq ft range which imo is ideal.

I would run 8 of the QB120 boards, in a square layout with a hole in the middle. Power them at 40W each. This layout will give you the most uniform spread, with no hot spot in the center. 320W total fits perfectly on the HLG-320H-24A driver and gives you 35W per square foot.
8 of the QB132 in the same layout works as well on the HLG-320H-36A.

Is the boards mounted on an aluminum sheet??

No. No need. The QB120 and QB132 were designed to be run without heatsinks. Just attach them to some aluminum channel for support.
Flowering only light....2700 or 3000K..?

Yes. both the 120 and the 132 are less than 12" on their longest side.
