Ordering DJI Pocket 2, accessories needed?

[NancyMoranG]

ordering it and wondered who might have one and can make any suggestions/comments.
Along with my Nikon D7000 and my cell phone, I am adding the Pocket 2.
My goal is to make more personal videos with music for family and friends.
99% are going to be outdoor, landscape, nature shots. Probably not much sound other than some small steam sound or an elk bugling type sounds.

I would like to get an extension stick to get some above the ground shots. Could it double as a small tripod that I can set up on a trail and show me walking into the frame on my hike type shot?
Am thinking I should get a polarizer?
Thoughts helpful.
