In EU your rating will only get lower if you actually don't pay for loans. I don't need to use credit card and pay it off regularly to get low mortgage.

Bank ask about job and income information (for bigger stuff like mortgage) when you get the mortgage, not keep a file with your entire life's of financial information.

Ok for mortgage but I had in mind getting better credit cards in order to get rewards. I do want to give these companies what they want so I can get better rewards.

I'm not saying the trade-off is worth it for everyone, I'm just saying there's a trade-off, unlike in advertising.
