For zigbee dongles, take a look at the SLZB-06. I used a sonoff usb dongle at first (which was fine), but then switched to the slzb which works nicer and lets you run it independently from your home assistant machine over Ethernet (you can still use usb if you like though).
I have like 50 ikea zigbee lights running off mine (plus the same amount of other zigbee stuff) and it works super stable with zigbee2mqtt.
