I have found a simple 3-button-mouse (so LMB, RMB and MMB/clickable scroll wheel) to be absolutely sufficient for Blender.
I tried the Space Navigator for a few months. But honestly, the navigation in Blender is so straightforward, I sold it again.
Here is one of my most successful classes, a complete workflow "From Sketch to (printable) Model": https://skl.sh/3219zVE (from 2020 but still 100% doable with current Blender version!)
Or my "Blender for Absolute Beginners" class that is a bit more recent, a thorough introduction to Blender and creation of a simple 3D printable bird :)

(Both links give you a one month free trial of Skillshare, and you can watch the intro video without logging in)
I am a content creater and tutorial maker and I love how this app works! I use it for working with students through screen sharing as well. I think this app gives great accessibility functions as well as very good customizability for all kinds of tutorials.
The 7 day trial period drew me in, as well ;)
