Some other comments brought up that the heme iron in meat is better absorbed, which is true, see figure 1. But the good news is that Impossible burgers have heme iron. They make it in yeast by adding a plasmid with the heme biosynthesis enzymes, pathway in Figure 1 of their patent on the 56th page of the pdf.
Also oysters and mussels can have a decent amount of presumably heme iron, and they seem unlikely to be significantly sentient, and either way, your effects on wild arthropods are more important in your diet choices. I’m vegan except for bivalves.
