I’ve never had a WFH job and I generally don’t think I’d personally want/be successful with one. My sister is fully remote and she actually hates it, but I think its more the job she doesn’t like than the WFH aspect. She says its lonely and isolating on top of disliking her daily tasks. I’m not anti WFH for others at all, to absolutely clear.
The lunch thing is definitely something I miss, and the white board collaborations. I haven’t found any decent equivalent virtual tool for the latter, and if you’re starting a new job in-person collaboration can be a jump start.
That said I’ve worked remote for a decade and the pros outweigh the cons greatly. A huge perk for me is being able to workout at lunch in my home gym. I’m not a morning person and I’m often so drained by end-of-day that working out after work is a non-starter. I know my physical health would be worse if I had to go into an office because I just wouldn’t end up working out like I do now.
