I second the smart switch strategy, especially when using a fixture with several bulbs.
As for ZigBee however, I've been using Home Assistant Yellow with its built-in ZigBee radio and ZHA, and it's been flawless. Any issues I've have been a matter of reinforcing the network by adding a few smart plugs. I got over 60 devices hooked to it at the moment. Z-Wave has been just as problem-free. The really nice thing about having a Z-something network is the ability to use low power devices like battery powered sensors and switches/controls. Want a smart doorbell that plays a chime on all speakers and sends you a phone notification? Stick any ZigBee button to the outside of your door and program the automation. Its battery lasts two years.
Reading this thread as I'm beginning my home. automation journey. When I first asked most people. also said focus on switches / plugs as your smart source.
Would a smart switch be able to do color FX with bulbs? what kind of bulbs would I have to get if this can work?
Not as far as know. The bulbs would have to be smart themselves and connect to HA directly. Switches are more useful when you want to switch a few lamps and don't want anything but dimming. They can make that cheaper, especially when switching 6+ bulbs. I use Z-Wave (a coincidence, ZigBee works just as well) dimmers for three such fixtures. For smaller 1-2 fixtures or when I need color I use smart bulbs.
Altough you are right about this and I do also still have a zigbee network for these purposes, I did observe range, repeater, and stability issues. For light bulbs, which are not battery powered, there are more options to consider :)
