There are plenty of mobile ryzens with a TDP of 15W, I’m not suggesting a Threadripper for a tv box, that’d be crazy :)

The -U (“ultrabook”) Ryzens are found not only in laptops but also in mini pcs, very efficient (yes even at idle, I have a power meter) are also the -GE and -G APUs despite the higher TDP (35W and 65W) because of their monolithic design. And in mini pcs the system consumes less power compared to putting the same cpus on a beefy ATX motherboard with a hungry chipset and inefficient VRMs.

Intel+TSMC mobile/embedded cpus are also great choices, same concepts apply.

I should have written desktop environment (DE) and not manager (I mixed it up with WM, window managers), btw they’re not just for actual desk-top computers, some are even optimised for the TV (and input with a remote). I misunderstood that you felt a need for a lighter software setup instead of simply preferring it, my bad, and kudos for making sensible choices, bloat is bad. Happy linuxing.

I share the general sentiment but lower TDP does not equal lower consumption, any “mobile” ryzen since the series 4000 on Zen 2 (7nm) is more efficient at most tasks than an N100 (10nm TSMC node), and barring specific mobo issues all have in general very low idle consumptions. But their iGPUs are a lot more capable, faster at anything, no need to limit yourself to a lightweight Desktop manager. Shop used and you might get more bang for your buck with an older ryzen mini pc than a newer N100 one.
