It's the other way around... MSW for everything but electronics. SOME microwaves have problems with MSW. My theory is this... Plug it in and see. I know a lazer printer is Pure sine only but an ink jet is just fine on MSW. It's mostly "some" that don't like MSW on electronics.
MSW will power most anything. Start with MSW and if something objects, buy a little PSW unit. But I am a firm believer in using multiple inverters (that must be kept within 10 ft of battery bank) rather than one large one. I like to know that if one unit poops out, I can pull another unit into service temporarily. But mostly it's because I have one 750Watt(?) inverter now and may add another one later. One for lights and front TV. One in the rear for desktop computer, printer and rear TV. I don't really NEED the 2nd (rear) inverter but I would like one.
Figure to DOUBLE running watts for startup motor surge (minimum estimate... to be safe 2.5X and figure the fridge runs 24 hrs for load)
