Put the Sony GX7 recorder in the closet. For this project, it is useless.
You want lossless recordings to do all of what you want.
1. loss capture, process (deinterlace, NR, overscan masking/cropping), H.264 encode
2. preserve (archive/masters) as lossless, or at worst high bitrate (15mpbs+) 4:2:2 MPEG-2
3a. edit requires lossless for your sanity (compressed editing is a nightmare)
3b. sharing is the same as watching on smart TV, unless you mean to share archive/master files for them to edit/restore
Hardware required = VCR > TBC > capture card.

I need to write the inverse of that article, but it states what a basic DIY home/office setup entails.
Buy it, use it, resell it.
It won't be that advanced. When you have good hardware, it just works. Every corner that is cut results in more workarounds and headaches, and lower quality. And then you have all of us in the forum to guide you through it all.
I can build minimalist (some corners cut) workflows for about $600 right now.
Ideal/better are about $1000-1500.
The best is about $2300, but I can only make one of those. (And that's what my own hardware looks like.)
Just so you get an idea for costs involved, as of May 2020.
