Finder is the number one reason it boggles my mind that people claim macOS as head and shoulders above other OSes "for professionals". Finder is a badly designed child's toy that does nothing at all intuitively and, in fact, actively does things in the most backwards ways possible. It's like taking the worst of Explorer (from Windows XP), and smashing it into the worst of Dolphin or Nautilus; and, to top it off, then…
It has been more or less the same as long as I've used it (20 years or so). Familiarity is a plus. It is a pretty simple and straightforward tool. I'm not sure what you might find perplexing about Finder.
Back/forward operate on history, not on hierarchy; at least have an "Up" button. There's no easy way to navigate the non-prescribed folders without adding every folder to the favorites list; hell, there's not even a "Home" link by default. Simple location navigation is hidden behind Cmd+G versus being evident. Easily jumping up the tree from your current location is hidden. Etc, etc, etc. It acts like the iPhone file manager, except the filesystem isn't a sandbox on macOS and you regularly need to navigate around it.
I'm sure if it's the only FS manager you ever use then it's just fine and you've learned all the quirks. But for people that regularly use other (better) managers on other OSes, it's severely lacking in ergonomics and functionality.
