Some help please:
A standard microwave produces 100% power, but cycles the magnetron on and off during defrost. It also provides no browning ability, which is needed for say cakes and roast meat.
An inverter microwave produces a constant reduced power for defrosting, with no pulsing on and off.
Q1: An inverter microwave has no browning ability, correct?
Q2: Is any microwave energy produced by the magnetron during convection cooking of roasts/cakes? Or does a convection microwave work exactly the same as one of those convection glass oven/air fryers, in that a fan just blows hot air over a heating element?
Q3: Do all convection microwaves have a rotating platter? Or are some just a four-walled box where the food stays in one position?
Q4: Can you cook/is it better to cook, cakes and/or cupcakes in silicon baking trays in a convection microwave, or in a glass hot air oven?
The inverter just allows the microwave to operate at different power levels, nothing to do with browning. You are correct.
You can choose - microwave and/or convection in any combination (I have one with "grill" too, any combination of the three modes)
"All" is a dangerous word to use. I'm sure at least one exists without it, but in general a home use microwave will have a rotating thing, although I think mine says not to use the glass plate in grill/convection modes.
Don't know
