Sadly, the current crop of keyboards and mice as not as repairable as the ones we had back in the early 2000’s. It all comes down to costs of manufacturing and trying to stay in the sweet spot people are willing to spend given the wow factor of the tech internally and the margins they need to live.
If you can I would stick with a wired keyboard and mouse.
As far as guidance beyond that we don’t really get deep into the peripheral devices, what you mostly see is contributions from people who wanted to add more to the iFixit collection.
