I'm in my early 30s at your height living in Nordic country as well. It's definetely in first quartile amongst the men, so you feel short when going to the public. Imigration averages out the numbers a bit. Try wearing high heeled shoes, prada cloudbust thunder, nike sacai's etc.
Regarding the loan, it will be hard to get consumer credit without no history, stable income. I just took a car loan, they asked 3 years of income declarations lol. Although with inflation, base amount should depreciate.
Regarding the work, I would be sceptical about 5k. in junior positions. With AI one senior dev can do same job as 2-3 junior devs. Not sure about your personal situation, but cost of living correlates with the salary too. Take into account healing time costs.
I'm waiting until Russia opens again, LATN externals used to cost there around 5-6 Euro with Solomin, but you will be offline <8 months if considering 1.5 months per cm healing rate. Giotikas is the next best value for money.
If I were you, I would go to Asia, Brasil where average height is lower, see if you are still struggling with your height.
