Can we talk about rice cookers?

I've always made rice in a pot on the stove and that's served me very well but I also like to steam vegetables, dumplings (usually from frozen), and eat oats for breakfast. After a bit of research, I've determined that I'm in the market for a rice cooker, an appliance I have never owned and have 0 experience with. Like most kitchen gadgets, I find that the market is oversaturated with options and my attempts at research have led me to some wildly different conclusions. Do I stick with brands I know like Cuisinart or KitchenAid? Do I spring for the fancy Japanese brands? Or do I cheap out and then upgrade when the device burns out? How large of a volume do I need? Are the fancy steamer inserts worth it? What if I want to steam rice and veges in one go? And so on

For my personal use case, I make rice 3-4 times per week easily. I need to be able to make enough rice for 4-6 adults max in one sitting. I would like to make a decent amount of dumplings in one go, say enough to get 4-6 adults started while I steam a second round. I want to be capable of steaming veggies and making oats. I want it to have a removable insert for cleaning. I'd like it to be fairly easy to use. Are these common wishlist items for a rice cooker? I am really not sure

Beyond my use case, I'm interested in what people own and use. Do you use it often? Any regrets? What other foods can I make with this gadget?

Edit: I appreciate everyone who has weighed in so far. I did want to add that I prefer not to add an instant pot. Not to discount anyone's experience but I have had bad luck with them (I've had a pair that burned out in the warranty period, one on its first use) and already have a slow cooker and pressure cooker cooker I am very happy with. I know they're amazing and do all kinds of different things but I'm interested primarily in a rice cooker that can handle a few extra tasks
