I’m currently having a go at Blob Fusion by @JoseConseco. It was the first SDF add-on for Blender, and it has recently been updated.
I particularly love the fact that you can add any Blender mesh as an SDF object, and it’s dynamic as well, so you can adjust the source mesh and/or its modifiers, and see the derived SDF version auto-update. 
Please note though that the live-linked mesh-to-SDF conversion requires heavy computation, using Blender’s native Geometry Nodes volume / voxel functions, so it’s best to stick to Blob Fusion’s SDF primitives as much as possible.
Other features include coloring of elements, and a full hierarchy, making it similar to how ZBrush ZSpheres or Blender’s Skin modifier works, but on steroids.
And… Contrary to the current version of ConjureSDF, Blob Fusion works in Blender 4.0+, and should also work in Blender for macOS! 
Have a look at this video:
