Another old addage from NJ....
"Drop ceilings hide a multitude of sins"
That said, cord thru the tile is a no-no. A ceiling grid mounted box, suitable coverm strain relief, & TL is accepted
However, a TL recept mounted in the ceiling box, face down, that the cord from the equip plugs into may be a better way.
Some AHJ's cite the cord from the ceiling box in the first scenario as using cord for permanent wiring, and red flag this, absed on 400.7 & 400.8 interpertations.
