I am surprised how good the range is of the SLZB-06, where Philips Hue gateway has connectivity issues due to the distance /concrete walls, the SLZB-06 works flawlessly with all zigbee endpoints. So in all, definitely can recommend the SLZB-06, HA, Zigbee2mqtt, Mosquito route! The only steep learning curve was me avoiding the docker installation of HA, so I had to install all components myself. That can be solved to learn the ins and outs about docker, right now I do not trust docker. Also what i additionally like about the SLZB-06 is that the SLZB-06 can be connected to via ethernet powered by a POE injector. My HA, MQTT broker and zigbee2mqtt installation are virtualized so i do not have to worry about USB hardware being forwarded to the container, because all traffic is over Ethernet, nice and stable!
