First off you're confusing requirements to get a visa from a thai consulate in your country before you come here with the requirements to get a visa issued at the immigration office inside the country. They are completely different, you do not need back ground check, you do not need insurance proof.
Also you cannot get a 7 month visa 😕 Sadly (unless I did the conversion wrong)

SEK is not 65k baht a month so you would have to bank 800k baht in a thai bank account in your name only to get the visa issued here. 🙁
GO to the Chiang Mai Immigration office and get the requirements for the "retirement visa". s
You don't do anything at the swedish consulate in C/M you get visas for thailand at the immigration office.
I think though with the financials you mentioned you will not be able to meet the 65K baht a month requirement if using income from abroad.
