Depends on the role, but when you apply for jobs, you can search for 100% remote positions. Might take some work, as remote can be a luxury that comes with experience in the field. Pretty much any office job can be done remote, and where “remote “ Is can change day to day if you like.

Not sure, tbh. I think it varies from company to company. Some require you to be stationary, others don't seem to mind as long as the job is done. You could also go the freelance route, but often times, like any self-employment, you're chasing money to make money.
