Hallo @Trombonick ,
Most of the Zigbee switches that are sold on AliExpress and Amazon are supported in Hubitat. Some of these may work with HE inbuilt Generic Zigbee Switch or Generic Zigbee Multi-Endpoint drivers, others will work with community-supported custom drivers.
It is very difficult or almost impossible to precisely identify what is the exact model of such a device based on the pictire or even based on the AliExpress/Amazon link. Read the comments from the customers who has purchased the particular product, if there are comments saying it works OK with Home Assistant - then the chances to work with Hubitat are also great.
I am also using Philips Hue bridge to control almost all of my home lights, it works absolutely reliable! My bulbs are a mix of Philips Hue, Osram, Ikea, and Chinese Zigbee bulbs - all controlled by the Hue bridge. I use CoCoHue community integration with the bridge.
As most of your bulbs will be always on, you will actually not use the relays inside the switch modules that you are going to put inside the wall boxes. So for simple on/off commands to HE hub using your existing wall switches you need to use the S1, S2, S3, S4 inputs. A lot of similar switches are supported by this community driver : Zemismart Zigbee 1/2/3/4 gang light switches . The link to the latest driver version is posted here.
Zigbee dimming modules are a bit more complicated. Do you want to be able to dim the Hue bridge controlled lights locally from the wall switch? Some supported dimming modules can be found here : [Release] Tuya/Lonsonho 1-gang and 2-gang zigbee dimmer module driver
On the window blind modules - do you have existing motorized blinds and if yes, how do you control these at the moment?
The Zigbee Curtain Module from your screenshot may be difficult to use. Currently, there is no driver for Hubitat which will handle the procedure of setting up the curtain motor limits (the time needed for full open and full close). Here the solution is again depending on the particular blind motor model - some come with a dedicated remote control unit that can be used for setting up the limits, and then you can use HE to automatically or manually open/close the blinds.
An alternative approach (that I use at my home) is to not touch the existing wall switches - just fix them in the On position all the time. Then add battery-powered switches, that can be installed at a convenient place on the wall or elsewhere. Using battery-powered switches for simple on/off or scene switch control is easy, it is more difficult to find a good dimming switch in Europe. I am most pleased with Philips Hue dimmers and Osram Lightify dimmers, these can be found sometimes at reasonable prices on eBay.
