Where / how to learn about video formats

I have a new Canon EOS R5 C and it has lots of various formats that it can record in. My particular situation is I will never be in a time crunch so I will have the time to create proxy files or whatever else is necessary. Currently this is just a fun hobby and, maybe if something is taking a very long time, I will research how to speed up that piece but I'll cross that bridge if I ever come to it.

The other particular about my situation is I "never" delete photos or videos. The never is in quotes because if it is a complete waste then I'll delete it but generally I keep everything.

I use Adobe products: Premiere Pro, After Effects, etc.

So it seems to me that I would want to most compact format in whatever frame size I want to shoot. But with very little experience, I thought I would ask here to see what the basic recommendations are, rules of thumb, etc.

I realize that this is a huge, open ended question thus the original way I phrased the topic: where / how do I go to learn about video format, etc. And if part of that answer is "go do it", then, fine. I'll go out and experiment, etc. and see what works for me.

You go to Youtube!
preferably on a good size smart-TV

On many TV's, on just about any video you can "get-info" to via the stats and see just what resolution/frame rate you're watching.

Plus you can also search for specifically made comparison videos as well, that talk about it. like this one

there is no rule, as everyone has a different preference.  some people prefer shooting 4k, others just 1080 (or even 720), some prefer the look of 24fps, others 60fps. and some find the middle ground of 30fps works for them. a lot depends on what you want to shoot and the look you want to go for.
