For one thing, if you want to go the breaker route, you can get GFCI breakers for your existing box (just make sure you match manufacturers because breaker panels aren't standardized. A Square D breaker won't fit in an Eaton panel). This adds GFCI protection to every receptacle on the circuit but does require you to identify the neutral wire for that circuit and move it to the breaker.

If you go this way though, you are further investing yourself into that manufacturer's ecosystem.

The GFCI receptacle adds protection to the receptacles down the line. It also adds the benefit of having the test and reset buttons in a convenient location. This does require you to determine which receptacle is 'first' in the chain. So you don't need to replace every receptacle on the circuit to have the protection.

I hope this helps. FWIW, I am not a licensed commercial electrician. I deal with electrical supply professionally, but it is all temporary distribution, so we don't deal with the same codes and all of the infrastructure is in the open.

Is anyone considering that OP has a problem with CO2, as posted? I know my apartment isn't particularly well ventilated. This can be an issue for me in winter when opening all of the windows is undesirable.

OP you need to find out, right now, if you have a CO problem. If it is CO, call the fire department and GET OUT. If it is just CO2, most hardware stores have a little thing you can use to prevent your windows from being fully opened. Window fans placed in a window can help circulate the air with outside air. It raises your heating bill but beats suffocation.
