Here's some broad generalizations, but it's how I see things:
My bottom line opinion is worry about the storytelling first, then fret about all the other junk. The craft and gear will fall in line behind a great idea. If you know the shots you want to create to tell a story, you can usually find a way to make even the cheapest camera/mic effectively capture it.
On the other hand, if you come at it from a mostly technical side don't expect compelling videos that will enchant a layperson viewer.
Walking around street shots of Berlin, London, or L.A. with a new camera is great for us here at this forum, or for people that are into gear-porn. Heck I love to see what new tech offers too, but it's a snooze-fest for a regular person that watches those types of videos. The technical side of the craft is fun, challenging, and exciting, but if you want to really be a filmmaker it's not what you put at the top of the priority list.
Real film makers aren't making movies for those of us that dig that stuff, they're telling stories to a much broader audience.

...and you'll be a step ahead of so many others in the low-end side of the biz that seems more concerned with buying things rather than making things.
Just about EVERYONE in the modern world can get access to gear that has the capability to make astounding images and tell great stories. (They carry it around in their pocket and call it a smartphone) I'd argue that the majority of people with this new affordable gear don't make great stories with astounding images. So you really got to ask yourself ...which one of those people do you want to be?
I'm making a short right now with a used $200 GH1 and a $20 prime lens. The image is ridiculously good. I mean...it's nuts what I'm getting for less than $250. Which is cool. Great. I'm not worried about the image. I trust what I can get based on the quality of the gear and the skills I've acquired. At this point what I worry about is the story I'm trying to tell. Is what I have my characters doing interesting to the viewer? Do my frame compositions covey the proper emotion that helps support my story?
Having a Sony lowlight camera or Panasonic 4K doesn't mean squat if you don't do anything interesting with that capability.
My advice about gear and kit: Don't worry about your gear and kit. Get what works well enough and then use it. That's my rant and I'm sticking to it.
