This suggestion won’t guarantee you anything, but maybe consider the businesses where you’d have an advantage.
Any place where a current employee gives you a recommendation.
Any place very close to where you live, because they will assume you are reliable. Especially if you can walk, bike, or roll there.
A business that uses computers, but doesn’t already have plenty of people with the same background as you. In other words, if you’ve only applied for helpdesk roles with large companies, try applying to work at the paperclip-manufacturing company that’s a five minute walk from your home and that you never knew existed. Your job might be to answer the phone or pay the bills, but if you have computer skills then that might be the reason they hire you.
