We have had to do that, yes. It does take a bit of research and getting your head around doing things in a new order/new processes.
We have two airfryers a combi microwave/convection oven and a portable two ring hob.
One air fryer is a dual draw jobby, the other is a two lids to choose from, one does air fry, one does pressure cook/slow cook.
So between those (the dual drawer job lives out on the counter all the time, the microwave has its own slot, everything else goes away in one cupboard between uses) we batch cook loads of stuff.
I invested in a big set of glass dishes with cliplock plastic lids so they can go from freezer to micro or airfryer. (If you're better at remembering to defrost things you can just get metal trays or throwaway foil trays which go straight in teh airfryer)
We do the saute then casserole type things in the instapot slow cooker/airfryer, so bolognese, shepherds pie, chilli etc..
Spud can be done either on the hob or in the instapot once the meat is done, for the cottage pies/shepherds pies.
You can saute and casserole in most airfryers as long as you can take the little plate out of the bottom that raises things off the bottom of the pan/drawer, so we do that sometimes and do big batches of fried onions or roasted veg.
I also do anything id fry that really wants an extractor fan if you were to do it in a pan as we now don't have one... so burgers and steaks come out really good and no stinky kitchen!
If we didn't batch cook AND need an airfryer I can use by myself (I can't use the pot style ones only the drawer style as using a wheelchair, I am too low down to reach in over the top of it), we'd just have the drawer style I think, but DP does like to slow cook big vats of chilli and curry.
My favourite thing at the minute is egg fried rice, reheated - so when we get a chinese takeaway we buy extra egg fried rice. Fridge it, freeze it til we need it once its cool. Then when defrosted it goes in the preheated airfryer drawer (straight in, no dish, crisper plate taken out)... get it properly hot, super hot so its safe.. then wang in whatever veg, cooked meat or meat substitute we want. Lovely! It means its worth it to buy a chinese takeaway (I only eat the egg fried rice, nothing else) and we can use up left over and sad veg, veggie sausages etc lingering in the fridge.
