Or maybe you don't, because the source was a DVD anyway, or something you recorded on your phone. Maybe you don't notice it until you see the same movie at a friend's place, and it looks "wrong" to you because it's got sharp edges everywhere. Maybe you never notice, because you're a frog in a pot, and the opportunity to compare them never comes up again. But regardless, this is a bad decision, and suggesting it to others is even worse.

Wut? I would love to see this mythical old machine of yours where h265 has "ease of decoding" over h264: it would transform our current understanding of basic math and/or electronic principles. :P Less disk space, sure. But that, no.
If storage is so desperate that you don't have a choice, then okay, h265 is the right "choice" [1], because it's the only one you have. But the rest of it - the misunderstanding that the quality IS the same, rather than just that YOU can't (currently) tell the difference; and that decode of h265 is somehow more efficient than of h264 just because the stream is smaller - is just plain wrong.
[1] Even then, the electricity you wasted downgrading the quality of your library would have bought you enough TB of disk to just keep the h264 version anyway, AND have a backup of it.
> Yet, I would like to know: should I be doing AV1+Opus instead of H265+Opus? AV1 encoding and decoding hit way harder on my ageing CPUs than H265.
You shouldn't be doing either. But in short, the answer is "whatever suits your current needs, and your best guess at your future ones". IOW, if the device(s) you want to watch stuff on can't handle XYZ, then encoding to that in the delusion that you're somehow "future-proofing" your library is just plain dumb in both the long term AND the short term. Similarly, if you expect that a couple of years from now you're going to build an HTPC out of a Pi5, or a retired desktop that's only going to have an IGP in it, or etc, AV1 is the wrong choice.
This isn't theoretical: I've been here before. Back when hard drives were measured in the tens of GBs, and I ripped all my CDs so I could listen to them at will. I chose ogg over mp3 because it was technically superior, and open.
10 years later, when disk space was 1/10 the cost, I had the "joy" of ripping all those CDs again: this time to FLAC, and then *also* encoding them to mp3 for the car and portable devices. The circumstances were beyond my control, and I'd made the "right" choice originally, but it still took literally months of elapsed time to do it, both times. If I'd opted for mp3, or aac, or opus, or *anything* other than FLAC last time, it would have been a mistake that I'd have had to either live with, or waste yet another substantial amount of time recovering from. That's the road you're going down now, except in your case "recovering from it" isn't even going to be an option. I really hope you reconsider while you still can.
Buy more disk space. It's cheaper, AND quicker, AND more compatible (since you're already in h264), AND better for playback. Literally the *only* scenario in which that's not the right move is if you're streaming your video over a metered network.
