Choice of self-leveling compound?

[Vedspisen]

I have poured a floor with loops and I'm about to finish the surface for flooring. To make it as smooth and nice as possible, I'm thinking of using self-leveling compound. There is a plethora of different brands and designations for floor leveling, making it difficult for an amateur like me to figure this out.

My question is; what should I use?

It needs leveling from 0 to a few millimeters, and it is a heated floor due to the underfloor heating (if that matters in this context?).

Regardless of which spackel you choose, you should turn off the heat, it shortens the drying time and makes everything considerably more complicated.
How large is the area in question?

I have cast this week and haven't turned on the heating yet. However, I want to finish the filling before it's time (about a month). About 40 sqm
