LibreOffice Calc is a robust and popular spreadsheet.
When downloading the LibreOffice Suite,
LibreOffice Draw is included along with Calc.
However, also worth considering is
Krita (pro painting/raster-graphics) and/or
Inkscape (pro vector graphics).
All of these programs are multi-platform and free and open source, and they are locally installed (on your computer), so there is no need to rely on the cloud.
