You may have better luck if you collect more background and info and come back with a more focused question and tell more about what you want to do.
As you looked through the list of bindings, you already know you can interact with HVACs, lights, outlets, thermostats, valves, audio devices, TVs and other home systems. You system can rely or wired connections or wireless, make use of DIY devices or interact with hubs of other systems. Your budget, things you own already, do you have access and knowledge to do wiring, etc etc will all make a difference.
For most devices out there, you will find some discussions here on the forum that will answer a lot of your questions. The search function is actually pretty good. Happy reading
Maybe I am missing something, but the question I posed – you might need to read it again – can only be answered by someone, who has already made sufficient experience with openHAB.
To retrace the logic for you: It certainly requires someone to have tried at least a few models in different product categories of several brands. I am afraid, searching the forums will not bring the result you have in mind.
If you have already made experience with certain brands, perhaps you can come back again and report your experience.
@things for example, did you see the results if you just searched the forum or the word best?
There are threads on best dimmer, best motion detector, best lights, best hardware, best audio solution, etc, etc, etc… if you searched a little further you will find threads that discuss specific questions, e.g., zwave vs alternatives, ESP vs sonoff, Hue vs other lights…and unless I misunderstood, with exactly the experience reported that people have from practice including those with hands on experience on more than one system… there are whole threads on what to do for a new house installation, etc…maybe you find it interesting
