Thoughts on the design of this prop in slot with inlets cutting through the airfoil?

looks as can be a nice flyer! In such a model, and with prop anyway standing in airstream, i dont see any reason for extra inlets through the airfoil. Air will anyway follow the airfoil to the prop without restrictions. I suppose you plan build it without been really thick, and a blunt leading edge anyway.
If beeing used a EDF fitted inside a model, yes intakes will be necessary, if such one is put in free airflow, no inlets needed (as your prop- version)

Each "edge" in front of a prop, particularly if it is close creates a "siren" sound so with 4 edges it will likely be more noisy for no real benefit. You would do better to move the prop rearwards to allow a smooth fairing over the thicker part of the wing so there was only single edge..
Of course whilst a "prop in slot" works it does costs thrust efficiency compared to a prop in free air.
Ever wondered why the vast majority of prop planes today have them facing forward?

Yeah I know prop in slots aren’t ideal or optimized, but I designed this one specifically for FPV and combat. I wanted the prop to be protected during collisions, and the FPV camera to have as clear of a view as possible. That being said, I’d still like to get it as optimized as it can be while maintaining the protected prop, clear view camera, and handling characteristics of this tailless diamond wing configuration. Do you think increasing the front to back length of the slot and moving the motor further backwards into the hole would improve the aforementioned issues?

I am sure concentrating on making a smooth aerodynamic fairing over the thick part of the wing will be significantly more efficient than any slot. Due to the boundary layer and turbulence the amount of air that ravels through a slot is much less than its simple area.
I would try to have the prop as far away as possible from the edges of the slot although for the use you intend it may be more important to achieve "robustness" rather than peak aerodynamics.
