Do such jobs exist in North America, UK, and Western Europe?

I have been working at one of the Big 4's "global" office (offshore back office, based in India) for a year now. This is my first job, and I have a master's degree in finance.

Although I have a fancy title, my job is essentially copying and pasting stuff into PowerPoint and Excel sheets (what they call "company profiles" / "pitch decks" and "trading & transaction comps").

My current plan is to immigrate to Canada (by 2023), start all over again, but this time in Information Technology. I'll start as a Helpdesk (Tech Support Professional), and hopefully in the next 5 years, I'll gain enough knowledge and skills to become a cybersecurity analyst.

Reasons for this career switch:

1. I'm not sure what sort of jobs will I get in Canada, with such kind of skills. I don't think such copy-paste jobs exist in Canada. I think they are all outsourced.

2. Even if I become super proficient in financial modeling and VBA, it will be a lot quicker and easier to land a tech job (an entry-level Tech Support job), as compared to an entry-level job in finance. Moreover, entry-level jobs in finance are usually sales jobs at banks and insurance companies.

3. Also, I'd be short of funds as a new immigrant. I won't be in a condition to wait for several months to land a finance job.

4. Demand for IT professionals >> Demand for finance professionals.

But last night, I had a thought. I know that quite a few folks working at such "global" offices (offshore back offices) are eventually sent to the onshore offices (US, Canada, UK, etc.). I have no clue what exactly do they do there with such kind of skills.

Can you please tell me:

1. What exactly do these folks do at the onshore (US, Canada, UK) offices, with such kind of skills?

2. Do such copy-paste jobs exist in North America, UK, and Western Europe? Am I missing out on something if I start all over again in Tech?

3. If yes, what are these positions/roles called? Are there any growth opportunities in such jobs?

Any suggestions are welcome and appreciated. Thanks!
