Purchase a DJI pocket 3 combo package. Your iPhone is good but an Action camera will make it easy. I am not a vlogger like you but I used my DJI Pocket 2 on my Thailand trip. Then I felt that it was really good to have an action camera. Although I sold that and I bought a DJI action 4 dut to run and gun shoot. But I miss my DJI Pocket 2 and I do not have enough money to own both Action 4 and Pocket 3. If you have a rent option, then rent a DJI pocket 3 and take your decision.
