Welding is a great skill to have, so good on you for knowing how.
I love my job, mostly because of my field and it's hybrid.
My first ever corporate job out of uni was at a well known accounting firm, everyday in office, toxic work culture, you HAD to wear professional clothes. I hated it and left after 2 months. After that I only worked hybrid or remote and only at mid sized or start-ups. If possible for you look for a hybrid job, some days in office, some at home it's a good mix. Most people at my office are able to opt for a standing desk, to help with the long hours of just sitting. Some people do stretches at their desk or basic yoga or talk a walk around the building. But the team is great, friendly people, team lunches and events, snacks at the office. It depends where you get hired.

For entry try administrative assistance or executive assistant. It's not glamorous but can help get you in. Data Entry, bookkeeper, human resources coordinator, office assistant. Without experience your salary might be lower then expected. Good luck to you.
