This was the major one for me, in addition to the other stuff you mentioned. The "always at work" feeling was reinforced by the management style of remote work being like, we expect you to be generally available to respond at any time in a 12 hour window, sometimes more (because everyone works their own schedules across multiple timezones). In an office this separation is clean, and if I'm responding to messages or working at home, it's generally accepted this is outside the norm and I'm perfectly free to just shut the laptop off until the next morning 99% of the time unless I am on-call. It's nice.
The first thing I did when I went back fully in-office was tear down my home office and turn it into a game room. I generally do not even use a computer in my home. Sometimes we have enforced WFH days due to various things or events, but I established the understanding with management that generally I will not be expected to work full days from home outside of emergencies and I take those days off.
I understand some people love it, and I have a good office environment which helps, but the downsides (general office annoyances, commuting, lunch expenses, clothing expenses, etc) way outweigh the downsides of working remote for me. I got severely depressed and burnt out very quickly.
