I reply all to all work related emails because people will add someone who needs to be aware of what’s happening and I may not realize this is important to them. If they don’t want to be on the email they can ask me personally and I’ll take them off the chain.
I never reply all (or at all) to company update posts (e.g. new hires/promotions/other bs). If you want to congratulate them do it privately. The whole company doesn’t care.
My cleaner just moves stuff to the side, cleans that area and slides them back. So at most it’s like a few inches from where it was before or in the same general area. We have a really sweet lady come once a month and it’s so nice to not worry about doing deep cleans. I do basic cleaning in between if stuff gets really dirty.
