Been using wireless keyboard for like 20 years now, never would use a charged keyboard because I wouldn't want to wait. Wireless keyboard are very power efficient, only have to swap battery once every half year. Don't really care about these "mechanical switches" and RGB, other than these, there is really nothing you cannot get from a normal office wireless keyboard compare to gaming wired keyboard.
Same thing for wireless mouse, also haven't used a wired mouse for 20 years, wireless battery is the way to go, all these rechargeable mouse are just a hassle, it's annoying to wait for it to recharge, and of course you need to plug cables.
Only thing I would still use wired is ethernet.
