What is the best strategy for returning to Thailand with a business visa after leaving during COVID-19?

Hi guys need some advice from this group

I left Thailand in 2020 and have a real estate company in Thailand just when I process my workpermit the Covid situation started

Now I want to go back to Thailand in April

To get a Business visa here in Spain is so complicated as I am not resident here and have the Dutch nationality as well all the paperwork from the company has to be sent here to me

So I was thinking to go back to Thailand on an tourist visa and maybe get an extension to organize all my paperwork and then go out of the country to Malaysia and do my visa there

My wife will get also first a tourist visa and then change it to an study visa and one year later get the retirement visa I don’t want to do the retirement visa strait away as I want to use the funds to bring back my business to life

What you guys think

For me you think is the best way to do to go to Malaysia at Thai embassy ?

For my wife you think I will case problem that she will have first a study visa and later change to retirement visa

Thank you
