You might want to consider looking into Home Assistant. It can’t do the voice assistant part (yet?) but if you get the right smart devices to go with it, you can be reasonably safe from the usual smart home product stopping working because the maker got bored BS.
Homeassistant + all Zwave and/or wired KNX devices + Wyoming plug in gives a full voice assistant suite with guaranteed compatibility free from shitty cloud services. The downside is the cost. For that you could go ZigBee with MQTT and have reasonable protection against vendor fuckary
