I'm going to differ a bit from others, falling in line mostly with @jabecker early in this thread. I'm not a fan of Lutron Caseta, mostly because I think they're ugly. Technology wise, they're great. Appearance wise? Not so much.
If I had sufficiently complex automation, the Pico might draw me in, but a Samsung Zigbee button is usually sufficient for my needs.
I'd also say, don't limit yourself to one single protocol. I think Zigbee and Zwave and Clearconnect alll have their places (as do WiFi and Ethernet). Pick the device that most suits your need or preferences, and then work on the mesh as you need it.
With regards to the Light Bulb debate. Use Hue/Smart bulbs where it makes sense, and Dumb bulbs where it make sense. I find that Hue lets me solve stupid wiring issues in certain rooms in my remodeled 1970s house, and is great for table lamps and plug-in light fixtures.
For the record, even where I use smart bulbs in ceiling fixtures (pots and ceiling lights) I use smart switches. If the automation is well thought out, then the switch is rarely an issue, and sometimes useful (as when the hub becomes unresponsive for example).
Elsewhere, I use decent brand dimmable LED bulbs and Zwave+ Dimmers. Likewise, in a pair of living room fans wired to the same switch, I use Hampton Bay Zigbee fan controllers, while in rooms with a single fan and good wiring, I use Innovelli LZW36 fan controllers (Zwave+).
To fill out my mesh(es) I use a mix of Jasco/GE/Honewell in-wall outlets in both Zigbee and Zwave+ flavors.
I lean towards Zigbee sensors, but have Zwave+ ones as well, similarly, I tend to buy Zooz and Inovelli wall switches (Zwave+) but I have a pair of Jasco Zigbee switches....
My suggestion? Try a few things, see what you like and work from there. These forums are invaluable, and it is definitely worth reading what's here. Just keep in mind, every house is different, both physically and in terms of the signal environment, and the acceptance of you and your family for all the trials of Home Automation.
Good Luck and Welcome.
