There's your 1st clue. Mon$ter is overpriced and marketing BS.'m always trying to get newer, "better" stuff and this especially includes cables. I recently spent a lot of money on very expensive HDMI 2.1 cables manufactured by Monster Cable and I've had nothing but issues with them.
Years ago I used to say that cables from mfrs like "M", "AQ", etc were grossly overpriced for what you got and one could find a cable that performed just as well for considerably less. That thought needs to be tempered a bit now because of the higher video demands, HDMI 2.1, etc. Cables, like hybrid fiber cables, which are the darlings of the HDMI world right now are not cheap. But given the technology that goes behind them, R&D costs, certification costs (if they are certified), marketing of the cables, customer support (if they are responsive) etc all adds up. I'm not saying that the profit margin is slim, because I'm sure it's not, but the cost nowadays is not surprising.I always recommend purchasing certified HDMI cables. There is no correlation between price and certification. Certified cables have a hologram and QR code that you can scan and see and confirm the cable passed tests.
I have personally used Monoprice certified HDMI cables for runs up to 25 feet and used their fiber optic cables for longer runs.
You can do a deeper dive into HDMI cables here. Is there a difference between cheap and expensive HDMI Cables? - Poor Audiophile
No, they don't. It depends on what you are trying to push. I have an ATV4k Gen1 and Gen2 and have no issues with passive, certified UHS HDMI cables for any of the HDMI 2.0b option sets. I don't use or need ARC/CEC and control everything on my two HTS's with Harmony remotes. I never had issues either with certified Premium High Speed HDMI cables.Apple TVs have compatibility issues with 8k cables. If you switch to a 4k cable you should be just fine. I had the same issue, when I first purchased my Apple 4k TV box. I had a spare 8k (expensive) cable lying around, so I used it for the Apple 4k TV box. I had no end of issues, with the box completely shutting off within 15-20 minutes. I even contacted Apple support, nice people, but no help at all. After weeks of absolute frustration, and about to return the box, I decided to swap the 8k cable for a 4k cable. This was my last resort. This instantly solved the issue, and I haven't had a problem since then. I reported this to Apple and they said that they would make mention of it to their developers. Good luck.
For HDMI 2.0b option sets it should work fine with no issues. eARC at 30' shouldn't be a problem but it can be for some connected devices. I'm not sure what you mean about the "10m directional with eARC". All active cables are directional whether they support eARC or not.Cable matters ultra high speed certified on Amazon fiber hdmi 2.1 4k 120Hz or 8k 60Hz. “Designed with Xbox”. Works great for me on my hdmi 2.0b avr and projector. The problem could be what is hooked to. 10m directional with eARC
I’m suggesting that cable. I have it and works great and supports eARC. When I bought it I was confused about whether the longer distances that were one direction could do eARC bc obviously that is the other other way. After tea search they are only talking about video being one direction. I bought the hdmi 2.1 bc it is ran through the ceiling and I wanted to future proof it. I spent too many days up there in the crawl space fishing wires.For HDMI 2.0b option sets it should work fine with no issues. eARC at 30' shouldn't be a problem but it can be for some connected devices.

If you have a cable that works as expected then stick with it. As far as future proofing goes, the use of a conduit, especially in the walls is really the only way to future proof because that makes fishing cables safer and easier. As video standards increase you will be upgrading your cabling so if you have a plan for doing that easily (conduit) you are about as future proofed as you can be. Besides, active cables have electronics in the connector ends and as such, can fail or have issues over time as do all electronic devices. It's not that common but it can happen. That's another reason for easy access it tight cable installations.I’m suggesting that cable. I have it and works great and supports eARC.
