Hello, and welcome aboard!
I hope that you will find us welcoming and helpful.
In terms of what to use, I would like to suggest a few themes.
- It's all about the mesh: whether you choose zigbee, zwave plus, or lutron or some sort of combination it's important to build up a good strong mesh. Here are two great documents about building a strong zwave and zigbee mesh:
How to Build a Solid Zigbee Mesh - Hubitat Documentation
How to Build a Solid Z-Wave Mesh - Hubitat Documentation - It appears that at this time (Feb 2020), although each type of mesh has it's pros and cons, no one type does completely cover the waterfront (with all the different types that you asked about). However, there does appear to be some favourites here. For lighting purposes, many have extolled the virtues of the Lutron ecosystem (Please note that you need the Pro version of the bridge, not the regular version). I myself have a small Lutron installation. Reliability, and dependability, and performance are excellent with these devices. However they are generally expensive and their appearance may not suit everyone. In terms of Zwave there are many very good choices: Leviton, Zooz, Innoveli, and others.
- Other devices: On this forum, it appears that zigbee door locks are more prevalent, with less issues than zwave (even though I have a zwave door lock without any issues). It also appears that in terms of motion sensors most people here are happier with the faster zigbee versions (Aduria, NYCE, etc.) than with the zwave versions (Aeotec, Zooz, etc.).
- One of the really great things about Hubitat is that it's very flexible with the type of devices that it can handle. Check the compatible devices list before getting anything:
