Looks good but a suggestion to keep the changes a lot smaller, and the samples easier to copy

As an alternative you could have used the calcite font here, and used the content property in the buttons.

So this one would way <Setter Property="FontFamily" Value="{StaticResource CalciteUIIconsMediumFontFamily}" />

And for setting the content property use for instance Content="{StaticResource CalciteUIIcons_Glyph_AnnotateTool}"

You can find the full list here: https://github.com/Esri/calcite-dotnet-toolkit/blob/main/GeneratedResources/WinUI/Icons/Glyphs.xaml

Also the font size is best at 24 for this font.

Oh thanks! That just solved a bigger issue with the Maui calcite branch that I've been running into
