I have the "all of them" going right now. Home Assistant was used to bring automation to a combination of Tuya-compatible Bluetooth & Wifi devices plus very few Homekit devices I ended up with, and some Google Nest Minis but that software isn't what I need it to be on my phone, watch, and Macbook. No AppleTV or Homepod at the time so HA let me do quite a bit.
Then I brought in Zigbee thinking I was going to keep everything off the cloud. But I ended up with a Homepod Mini anyway. It fills some holes in HA. Now there's such a mix needed to be consolidated though.
I don't actually want voice control but I'm deep in the Apple ecosystem so I'm going to make use of it for notifications and quick control from my watch.
Zwave sensors will define my entire space once I can ditch the Zigbee stuff, or keep it, we'll see.
Walk into room X and have lights turn on with colour temp and intensity based on time of day, with a delay after human presence is no longer detected before shut off so it's not on off on off if it's many trips while cleaning or doing laundry.
Space heaters and fans will stay on outlets (or IR blasters) controlled by presence and temperature to compartmentalize areas.
Lights will likely never be on switches cause almost all are RGB. What started as TV bias lighting turned into "room tinting." That's where either voice or the Home app comes in. But it still keeps my devices off WiFi or BLE (even though I have the network to suupprt it) and gets out of the Tuya/Smart Life/Random Amazon shit environment and only iCloud. Home Assistant and Z-lighting brings back some of the lighting features lost when WiFi lights are added to Homekit directly. We're too far away from Matter being there.
I think that should meet the function, security, control, and notification requirements for me.
