ComponentOne has a more affordable DataGrid for MAUI. It's called FlexGrid - you can just grab it from nuget.org and start working with it. https://www.nuget.org/packages/C1.Maui.Grid

What's nice is that you can customize the grid line visibility so you can achieve a clean, mobile look, or keep the gridlines for a classic datagrid look. The control has star sizing, so the width can always fill your screen and not require horizontal scrolling (not ideal on mobile).
