I will probably be alone in this. For most people, I tend to think a full-blown camera is overkill and disproportionate use of a $2,000 budget. There are so many things to make your life easier. Having a complicated camera is not one of them although people love the aesthetics. I would splurge on an iPhone probably for the video quality but keep the portability. I would entertain a GoPro if I was willing to burn some money.
I would start with a great Microphone, a nice comfortable chair, a big monitor, a full desktop PC for good bang for buck for editing & rendering video (NOT a laptop), an easy to use video editor, a thumbnail creator tool like Canva, some ring lights, perhaps a nice set of room lights. $2,000 is a huge budget to "get started."
