The copious amount of joints that are held together by the fasteners only and the non-structural deck are not going to like that long term.... but it's also a home office so it really doesn't matter what sins you commit, it'll all survive anyway.
That said, a plywood deck that is glued and screwed down like a subfloor pretty much absolves all sins.
For most projects, glue & screw is fine. It's cheap and low effort. I use it in every utility project because speed > looks. I've never tested it, but I'm pretty sure that connection would be stronger than the wood itself.
