My father-in-law uses a breathing machine while sleeping so I didn't want to run the generator all night for that, a fan and a few lights. I'm not intending on running the air conditioning but need AC (alternating current) without the generator or shorepower.
OK. Your major problem will be your power budget to do that. Your lights are already 12 VDC so the inverter is not an issue. Ditto built in fans or 12 VDC equivalents are available. You are better off using as much 12 VDC as possible as conversion to 120 VAC costs power due to conversion losses.
Forget the microwave as it is a huge draw when running. You are better off just starting the generator that needs to run anyway.
You have two options on the CPAP. Some are 12 VDC units with an adapter brick and some do need 120 VAC but are not huge current hogs so a small inverter will do the trick. The issue there will be enough battery to cover the power use overnight. How many batteries do you have for the house?
Depending on what else you want to run my general thought would be cell phone charging and similar small loads can go on the CPAP inverter. They are really low. Better yet get a car cord that needs 12 VDC. Higher loads like laptop computers are still low enough for either the CPAP inverter or a second one. They also do not kill your power budget. Forget about any high current loads like the microwave, hair dryer, coffee maker unless you plan on running a very large capacity battery bank. In general it is much cheaper and easier to cluster their use and use the genset.
To go on from here it takes knowledge of house battery capacity. You need to know that to plan the CPAP. Having said that two batteries are probably marginal, more sufficient unless you really suck power for something. That is a general observation of many similar threads.
