What would u recommend?
We know The TT industry goes full out for ultra light. We can count on repeated questions concerning set up stability. How about redoing corner jack stands to substantial post that are truly funct...

Some of the early "light" TT used some kind of "composite" floor. They became very soft within a year ot two.
Most (all?) have gone back to 3/4" plywood.
Not true at all.
When people are talking composite floor, that's composite as in laminated. Beaded styrofoam in between an aluminum tube structure, with plywood laminated top and bottom the same as a sidewall. Typically a little thicker on the tubes and foam than sidewalls, 1.5" or 2" foam as opposed to 1" on the sidewalls, and 1/4" or 5/16" plywood top with 1/8" plywood bottom. All laminated together with contact adhesive and either pinch rolled or vacuum bonded.
Plenty of manufacturers are still using laminated floors. Chances are if your trailer has laminated sidewalls with a fiberglass / filon exterior, you also have a laminated floor.
Midway of the 2017 production year Forest Rivers Rockwood division eliminated laminated floors and went to 5/8" plywood, actually OSB. According to a Rockwood rep I discussed it with at the time, that was done more for savings on manufacturing cost than problems with the construction
I can not prove my position or your position, but my research shows that most companies are using plywood floor, even it is because it is a labor cost savings.
As was mentioned elsewhere, composite flooring requires more reinforcement than 3/4" plywood.
One last thing, if you look at spec sheet from the manufacturers of composite materials for RV wall construction, NONE OF THEM APPROVE IT FOR FLOOR CONSTRUCTION.
