A few positions could be posted on nav.no (government social security firm), but it's not really worth checking.
For language, if you're serious, I'd probably find a Discord channel for people wanting to learn. It's literally how I met the missus.
We all learn differently, but finding someone with a shared hobby that you can talk to while doing said hobby is effective. We had gaming in common.
Talking is, at least for me, a million times better than reading and studying.
Best of luck to you, and let me know if you have any questions.
And: it's not utopia here. We have issues as well. Just make sure you remove any rose tinted glasses before comitting countless hours.

I also very recently started understanding why they hated smartphones with small screens as they typed so slowly, as I keep mis-typing more and more myself.

Becomming a parent slaps you with another big load as well.
