Jack I don't know mini tripod, but i watch on internet and saw many mini tripo for : Reflex / mirrorless and phone. I will watch this during black friday I think
Many times I shoot at home, I take my tripod but I shoot something on a table, so it will be easier with a mini tripod on the table
that's what i do actually but it's easier to take a mini trip than a big trip I really need to buy one ^^
I've a small travel tripos as well (Rollei M1-Mini tripod). It's really very small but stable enough for my Canon EOS 90D.
I use it mostly together with a Manfrotto clamp to fix branches or my flash light. Very useful but not the cheapest one!
I screwed a arca swiss compatible mounting plate below the manfrotto clamp. So you can mount the clamp the same way as a camera.
I made a picture for you for a better understanding:
