For a Dobsonian, a 90-degree, 8×50 finder is much better than any 180-degree finder. You don’t have to bend down to look through it, which may seem like a no-brainer, but most companies send flat finders with their Dobs. Zhumell thankfully sends a 90-degree 8×50.
As I’ve mentioned before, the 30mm, 2″, wide-field eyepiece is very good. It is superb for deep space performance. Again, most companies don’t send such an eyepiece.
The 9mm is not anything remarkable. It is the usual, planetary, 1.25” eyepiece. I recommend changing it with a Goldline in the future.
