Does anyone know how can I get a more flat bedmesh based on my results? What should I look for?

You should look for acceptance. <0.2mm over a 350mm bed isn't at all bad.

I see, but should I try deracking it again or it would be overkill?

There's really not much you can do to mechanically fix errors that small, and the bed mesh levelling is more than capable of compensating for it.
An error of a couple tenths of a millimeter is as good as most people will ever get, and I would be perfectly happy with it. My 300mm 2.4 has a total error range of 0.17mm (larger printers usually have larger errors), and I wouldn't even attempt "fixing" it as anything I do is just as likely to make it worse. And prints come out perfectly fine so why bother.
