If you want to film at your computer, any 1080p webcam will suffice. I have a Blue Yeti for my recording needs but a Snowball is probably fine to begin with (I was interviewing and podcasting so I wanted something a little beefier). If you are going to film away from your computer, your phone is an amazing tool that will deliver time and again. I used a Sony Handicam for some stuff way back when, which I enjoyed because the screen flipped around and I could stay in shot. The newest iteration is about $190, but there are always sales.
Editing, I use Filmora. I find it intuitive and really enjoy the available options for fonts and credits, etc. You can always purchase more items if you find the available stuff isn’t extensive enough. I paid for it, got it during one of their sales for around $39. I use Bandicam for screen capture but OBS will do nicely if you’re just starting out.
Just my two cents.
