Hope the information there can help you find something. Freehand takes some time to get used to but isn’t always as daunting as it looks.

And systems can be limiting, but again there’s plenty of information and posts about anything related to keeping a sharp edge on your knives.

Head on over to r/sharpening and read the wiki.

Unless it’s a really hard steel, a Shapton is probably going to be the most suggested for price and performance. Not quite BIFL, but it’ll last quite a while with minimal upkeep.

I’d head over and check the wiki out, watch a few links. They’re a helpful bunch over there. Even more so for thought out queries that have done a little research.

Edit: I missed the “system” part, but the sub and advice still stand. You can search for the systems you’ve been looking at and find some threads about them. Good luck!
