I think the trick is to try to keep appliances to a minimum.
You only want things that you will use EVERY day.
e.g., have two appliance in addition to the stove / range combo.
Instapot --you like wet foods, love beans and soup in particular, or are "anti" microwave
Grill (George foreman style ) -- you like to cook chicken from frozen, like quesidillas / paninis.
Convection Toaster oven - use a small oven for pizza, toast a lot of foods, occasionally bake brownies.
Air Fryer - like to roast things, meats and veg, cook typical air fryer things.
Fancy coffee machine -- you know if you are a coffee die-hard lover
Microwave -- speed and fast, low power, rice, leftovers
In addition to the essential to me microwave, I have tried the crock pot, electric frypan, instapot, Grill, Convection toaster, Air fryer at various times as my only extra appliance.
Each takes up a lot of space. I replaced the toaster oven and instapot (borrowed for 1 month) with the Ninja (top lid) air fryer. I use it to toast bread lightly (not as good as toaster oven), and lots and lots of cooking, especially roasting foods - bacon, roasted veg, dehydrating, meats, quesadillas. I have tried it to bake with here and there but the pan is small portions and I can't eat as much baked goodies anymore. I use this "air fryer" every day.
I did NOT like the instapot. Once I worked from home, the advantages of the timer / time off and fast cooking were moot as I could tend to a pot of stock or beans on the stove, and preferred oven roasted or braised to stewed / steamed types of foods. I don't eat a lot of dried beans, anyway, which is what it was the best for. It is a lot better / variety of foods than the crock pot.
When I worked and had kids a fancy foreman style grill was the go-to to get dinner cooked from freezer to table in under 20 minutes. (frozen chicken or chops or burgers or fish plus veggies).
A microwave is essential for all my "wet" food cooking, from rice to boiling water to reheating leftovers. It is always my 2nd appliance.
