I've viewed dozens of "top X smoke detectors of 2020" sites, and scoured the leading brands' sites (Kidde, First Alert, and Nest), but I can't find any that are battery operated, dual sensor (ionization and photoelectric), and interconnected (wirelessly). I can't install hardwired detectors in my home due to lack of access inside walls and ceilings. Many resources say dual sensor is recommended because they cover both smouldering and fast flaming fires. Additionally, it's now law that all new homes have to have interconnected alarms so a fire detected in a distant part of the house will be heard, which is a concern I have even though I don't own a new home. So why don't they exist with those three?

The obvious (but ultimately unhelpful) answer is that the heat/smoke from your cooking is setting off the alarm. So what you have to do is reduce the heat/smoke getting to the alarm.
There are a number of things you can do:
- If you don't have a smoke alarm in the kitchen close the door while cooking. This will stop the fumes reaching the detector.
- Use the cooker hood's extractor fan to help divert the fumes. If it doesn't have one, consider fitting one.
- If you have a smoke alarm in the kitchen make sure it's of a suitable type. The standard ones are (quite rightly) designed to be sensitive to any smoke/heat. A kitchen one will be less sensitive to heat (for example).
- Clean your cooker. This might reduce the particles being emitted. You might not be able to see them, but they are there.
I strongly recommend continuing with the AC with battery back-up models. They are required by code for new construction (in my area) for a very good reason- the potential for someone to remove the battery. Also, they are available with a wider range of features, such as described in your question.
This battery removal behavior is very common in rental units. So much so that landlords now are obliged to pay for replacement batteries, to remove any financial incentive for not replacing them.
Even if you will personally be in control of the units, you might decide to remove the battery for some reason, then forget to put it back. Most of the AC units let you know (with an annoying chirp) that the battery back-up is dead or is not installed, whereas "battery only" units just sit there dead with no indication to the user that it is not functioning.
10 year batteries are available for you to install in your AC w/battery back-up units:

No Demand
The demand for interconnected is associated with new homes in many jurisdictions. I don't know of any places (there may be exceptions, probably California if anywhere...) where they are required to be interconnected unless a home is new or, possibly, substantially renovated. When a home is new or is substantially renovated, it is easy to run wires between the detectors and to add wires from the first detector back to a power source.
So the need for "battery" is made obsolete by the need for "interconnected". You don't need battery if they are interconnected, you don't need interconnected if you are in a situation where you don't want to run wires back to a power source (because if you don't want to connect to power, you probably don't really want to run wires for interconnecting them either).
End result:
I don't think dual-sensor has much to do with it, though due to power requirements (and possibly a higher price-point) that may be more common with AC-powered, interconnected detectors.
I didn't catch the "wireless" part originally. For a bunch of reasons, I would prefer wired to wireless for smoke detectors. Wireless at many levels (from Bluetooth to WiFi to cell phones...) has enough problems that for life-safety I'd prefer wired, when practical. As long as this is new construction, wired seems quite practical, and new construction is the primary demand source for interconnected.
