> lack of visual boundaries between work and home life,

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.

I have my desktop computer where I do my own stuff like games in the same desk where I put my work laptop, and yeah sometimes it feels like I'm never really done as the transition is just closing the laptop and switch the monitor input, one thing I like though is that we do mob programming so when it's over it's truly over as we share responsibility rather than me having to finish something on my own before a deadline. But yeah I'm thinking of putting a second desk in another room for work, I don't want my own house to feel like an office.
