Hi Sebastian, the WhiteBox Tools looks great! Updating my QGIS (WBT works with QGIS v.3.18+) and hoping it will do the job!

There is also the Whitebox Tools plugin for QGIS (you need to install whitebox tools) that has a NaturalNeighourInterpolation algo.

Under Raster - Rasterizing, there is a Natural Neighbour algorithm. I have not used it, but I have used the Inverse Distance Weighted algorithm for magnetometry data which in essence does something like what you are wanting to do.
