It is always recommended to install cabinets before floating flooring rather than installing cabinets on top of floating floors. This lowers the risk of peaking in the future. Installing over glue down floors is not a concern.
It's always recommended to install cabinets before your floors if you are doing floating floors. You would not be guaranteed to run into issues if you did install cabinets over your floating floors, it's just that doing so would slightly increase the risk of peaking in the future as the floating floors are meant to have expansion space along the edges. With a glue down application, the cabinets are not a concern. Appliances are not a concern.
