I can see why it's a common practice for foam sheets to have a pre-scored grid and come with a attatched scrim skin.
That is for compound curved moulds, not for flat sheet infusion which only needs 2mm scores. This might be an issue with 3mm so you are probably better off using a flow medium. Soft shade cloth works well.
So If I went with a formular 250 1" sheet from Home Depot, hot wire cut it, I should sand the cut surface to open up the pores sealed by the hot wire, am I right?
Yes
Just to be sure, this is for a scale model use only so nothing critical at play for long term longevity.
Your call. Do a sample and see.
