the mouse shape is very subjective to the size of your palm and the style of your grip
sensors on gaming mice are pretty much all extremely good today unless you go super budget noname stuff, with no difference between mid and high range.
and the lighter it is, the comfier it is to use. lately we're seeing 70g or less. realistically anything below 80g feels light. I would not pick anything heavier.
cables on some models are so light and flexible these days, to the point where wired mice feel wireless
feet must be ptfe so they glide easy and a bit thicker so they last
for shapes and sizes you can look here, tho idk how updated the site is

if not sure, symmetrical designs have a better chance of fitting your hand
oh and I'd recommend optical switches, that completely fixes double clicking issues, usually found in Omron 10M-50M switches, which a lot of brand name gaming mice have. there's a hotswap option as well with Asus ROG mice, tho I think their shapes are meh.
keyboard wise, again, depends what you like, if you want smth to last you forever, you go either optical or mechanical w/ hotswap (lets you swap individual switches w/o tools and also fix various problems quick and ez diy). just makes it so you no longer have a disposable product.
otherwise, so many different switches and options out there, just need tot think about which type you prefer, minute variations between options of the same type will drive you crazy, don't even bother... lookup linear vs tactile vs clicky switches on youtube, see which you like and I'll find you a good deal
mby wait a bit till proper BF starts, there are always great deals on peripherals on BF, more so than on components
a lot of ppl just shop for peripherals at this time
