FreeCAD.
For those new to it, the YouTube channels I suggest for beginners include Mangojelly and ... <just search for FreeCAD beginners there are many videos available>.
I also rely on support from users in the official FreeCAD user forum since I began learning.
Probably all the mentioned 3D programs are considered. But in this situation - a container designed to fit a PCB card with fixed, rigid measurements - I would recommend FreeCAD instead of Blender (though I might not be entirely unbiased here, as I've spent some time getting familiar with FreeCAD's basics but not Blender).
In FreeCAD, the process would involve creating a body (a part defined by a clear 3D shape with fixed dimensions) that includes the PCB board, screw holes, and all components needed to form the box.
Using binders would help link these dimensions during construction of the box and lid.
Fusion360 offers a free version as long as you're not profiting from it. I've been using it for 3-4 years now. It also exports directly to Cura, which is a free slicer for 3D printing, or any other slicer program. You can also save the file to your desktop if needed.
