Additionally, it’s a bit more strict with certification so you can easily use multiple vendors for zwave whereas with zigbee it’s often a terrible experience since vendors implement things differently in ways that are not as interoperable. In fact, for a device to be certified by the zwave alliance, it must pass strict conformance testing to ensure backwards compatibility and interoperability.
If you limit your pool of zigbee devices to just more reputable companies, you'll end up with around the same amount of options as zwave and they'll be reliable but significantly cheaper.
You also have the option to find some super cheap stuff that works just fine. That usually requires some research but not much. You can also build ESPHome devices for zigbee but that's pretty niche, to say the least.
Having previously been all zwave then moved and tried to go matter but ended up with zigbee, I wish I never listened to people saying what you are. As far as I'm concerned, zwave doesn't know it's dead yet and Matter isn't going to fulfill it's promises because the corporate interests that wouldn't give you local control with zigbee aren't suddenly going to change their minds because it says matter now.

In the US you also have the FCC reshaping the 900 MHz for industrial broadband and NextNav. So there will be more competition.

They fix some problems but add more, you endup just like that xckd about protocols
If you're fortunate enough to not be battery constrained at most endpoints and can put a high quality Wi-Fi access point in an optimal location than Wi-Fi is incredibly reliable.
The tooling for inspecting all layers of a Wi-Fi network is infinitely more accessible and mature and that certainly helps; I can't go to My local big box store and get a USB thread dongle for 20 bucks that will just work on a Lennox computer and integrate nicely with Wireshark out of the box...

Wifi for anything but cameras is a mistake, it only exists for maximum compatibility since everyone has wifi already.
Buttons (key presses, remotes - think rapid input), Knobs, sliders, Pixel LED' strips, some MM wave sensors, ir/radio transmitters, really need wifi.
There is products where you will want a bluetooth proxy, plenty of kitchen/grill thermometers and scales for kitchen and bathroom are great examples.
Where range is an issue LoRa is a thing that has plenty of devices and is easy to DIY.
Two huge notables to me: message throughput for openthreads scales up, zigbee seems to hit a wall early. Not sure when that matters but very clear. The last table was a fright through: it takes half a minute for OpenThreads to recover after a node drops where-as Zigbee a quarter second! Wow.
