If you are truly new to this you are going to have to temper your expectations and dial down the complexity. Stage 1: Master your DAW. Learn how to capture, process and edit recordings. This alone takes quite a bit of time. Especially if you’re trying to incorporate musical (instruments) as an element. There is mixing, mastering and many other things to learn. Stage 2: Once your abilities in your DAE are fine tuned move onto finding better audio hardware for your environment and budget. There are many different ones with different profiles which suit certain applications. Vocal mics aren’t going to work as well as one that is recording an instrument. Stage 3: Once you’ve got your audio production up to your personal standards you would need to sort out your storage requirements and backup solutions for the projects you plan to produce. Stage 4: With all that in place you will then need to master a video editing application like Premier or DaVinci resolve. Like the DAW above you’re going to want to fully understand the software and basic editing principles before you make things complex with multiple cameras and angles. Stage 5: Now that you’ve got all that in place you can finally begin to look into video hardware. Cameras, switchers, lenses and lighting setups. More on reddit.com

Love that you are going for it, and honestly, you don’t need a huge budget to start. For the cheapest but decent setup, grab a usb mic like the samson q2u or audio-technica atr2100x, both sound great and don’t need extra gear. If you are doing in-person recordings, a simple two-mic audio interface like the focusrite scarlett 2i2 could help, but usb mics are the easiest way to start. For software, riverside.fm is perfect for recording and editing without needing a mixer or soundboard. it records locally (so no internet glitches) and makes remote interviews easy. If you wanna add video later, even a decent smartphone on a tripod works fine. Keep it simple, focus on good convos, and upgrade as you go! More on reddit.com

Opinion: Stay away from the Neewer stuff. I find it is cheaply made (boom arms etc) and will not last. u/chasingorange has good suggestions. I would avoid USB mics entirely since you already know you are bringing in another mic. My suggestions for solid beginner stuff.-- all onAmazon Behringer 1800S Mics (3 pack for $48) Any boom arm will work, just make sure it has some heft Cables and pop filters -- figure about $20 per mic. Get longer than you need and I am a fan of spending money on good cables Interface -- The Steinerg is great. Also look at a Focusrite Scarlett about the same $ You will be running USB out of the interface to your computer. You can use Audacity to record (it is free and some people hate it, but it does the trick and is pretty robust with a few drawbacks--but no sense spending $ on software to edit if you are not sure yo are going long term with this) I'd also buy a spare cable or two and have a few extra pop filters or foam filters--they go bad, get lost, etc and are not too expensive, but will save the day in a pinch.
