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.

Now I use this somewhat anatomical three button mouse from logitec: https://www.amazon.de/dp/B07W4DGC27?ref=ppx_yo2ov_dt_b_fed_a...

What I wouldn't recommend is one of those Apple mouse types, where everything is touch. In general, touchpads do not do well with Blender.

And the recommendation further below, getting a gaming mouse and mapping the numpad to it, is very smart!
