I often use Impress to build courses about technical drawing. For precision I use a grid with lines every 5 mm and 5 subdivisions so that I have a 1 mm sub-grid. I find this setting efficient: easy to measure at the millimetre level.
However, I sometimes need more precision, that is 0.5 or 0.25 mm. In this case I change the grid and it works well. But for drawing, and measuring easily, it's less convenient than with the previous settings. So once I finished what requires precision, I reset my grid to 5 mm, 5 subdivisions.
I think it could be really useful to be able to define several grids and to activate/deactivate them in few clicks, as proposed by Inkscape to give an example (Inkscape being less efficient than Impress/Draw for technical drawing in my opinion from my abilities).
LibreOffice is a very good tool for drawing and that should be great !
Thank you for reading !
Only one grid in Draw/Impress
Several predefined grid which can be activated/deactivated easily.

The better tool for those tasks is Draw. There is bug 125275 about the default resolution at tools > options > draw > grid, bug 125354 about isometric grids, and bug 78035 to define the grid per document (and many other).
Point is that we have a more or less flexible grid. And if we make this a customizable number it adds confusion.
There are also options to switch a grid on/off like using the master, a template, or layers.
My take > WFM. Other opinions?
We discussed the topic in the design meeting. While different grids are not easy to customize the use case is clear and affects probably many people. So the suggestion is to make it easier to change the values by introducing a UNO command that opens a dedicated grid property dialog replicating what's available at the sidebar.
