as others have said, major thing is federation, which is rolling out. other than that, the are mostly complete.

not really. it is more of, “i am not really motivated enough right now, can you please motivate me a bit?”

maybe programs liek navi (or any of the other billion snippets managers) can help you. essentially, these have list of commonly used commands, and then you open it with some keybinding, and you will search, lets say git commit (you know you want to commit, but lets say you forget that flag to give in line message is ‘-m’, then command git commit -m "message" would appear. you would select it, and it should either be typed into terminal, or copied to clipboard, or some other way to quicly enter it. some others do this by autocompleting from suggestions. I have something handrolled for the purpose (which is not in a state to be recommended to others), so i would say just search snippet/command manager/helper/complete, and you should get tonnes of them. i remember one of them, that is navi.

you may also like to check out fish shell (or if you do not mind setting up zsh, if you want posix compatibility as well), as it has a very superior (compared to ootb bash) autocomplete, which will complete commands, and their flags, and sometimes also gives description of what that subcommand/flag does.
