None of my TVs are connected to the Internet. That said, I could really do with a better open source fullscreen UI, especially since I mainly just want a web browser that works good. I'm just using KDE Plasma with a custom daemon to control the TV power state over an HDMI CEC adapter plus an old K830 keyboard.
I'm, frankly, a bit annoyed by this whole thing; I'd rather have USB adapter RF wireless because it is simpler to deal with vs Bluetooth, but actually I can't even find other Bluetooth keyboards that are as compelling as this K830 and worse yet, they don't even make the K830 anymore. I don't really mind KDE Plasma with just some minor customizations but I don't really like any of the options like Kodi. Maybe Plasma BigScreen will eventually be what I want for that. And finally, HDMI CEC is a pain in the ass. For reasons, I actually use an adapter to get CEC support on a normal PC platform, because most PC HDMI ports can't do it. And also, it's just a bizarre and overly complicated thing. I have it working reliably, but it took some time to iron out all the kinks, particularly because my TV responds quite differently depending on how recently it was powered off.
I really just want a big monitor and to basically just use DPMS... Like a computer does, but large computer monitors tend to be expensive and don't always have remote controls, which admittedly are handy.
As for remote control - why would you want one for the monitor. For the PC I'm using an Air Mouse which is just a remote gyro-based mouse with keyboard buttons with a driverless USB dongle that acts like any other USB HID. I also have a miniature no-name wireless keyboard with a touchpad but rarely need to use it.
I am not home at the moment but I believe the setup I got working was the Club 3D CAC-1080 Display Port to HDMI adapter. The trick, as I understand it, is that these adapters support tunneling the CEC traffic to/from Display Port AUX, and many of the Linux DRM drivers support this. It has been a while since I actually set it up, but I don't remember it being particularly hard. I have a couple different adapters that theoretically support CEC I believe but that's the one I recall working.

It certainly isn't strictly necessary, but it remains useful for input switching, and as a convenient backup option for power/volume. In the presence of a good fullscreen UI, I could see it being useful for basic directional input as well.
You can of course go the other way and handle input switching and all else via the PC, but that does mean if the PC isn't on nothing else works at all.
