I learned from experience that spending years at the same chair and desk can do even more damage. As part of my rehab, I switched to a laptop so I could move from couch to chair to table to standing desk easily. I also highly recommend using a motorized adjustable desk, now that goods ones are easily available and affordable. A perfectly customized height for sitting or standing is just a button push away, and I can use multiple monitors again.
There are manual height adjustable desks that can be set for near zero resistance moving up and down. They have a brake and an adjustable tension spring. I think those are the best ones. The only advantage (some) motorized ones have is the ability to remember presets.
For years I only used a laptop and I didn't really experience any of the issues you describe, I was very young though so that may have alleviated some potential issues.
Bit some cafés are very quiet, have delicious drinks and food, good music and are (IMO) perfect for some light to mild-focused tasks.
