Is there an alternative to Everything [1](file search with immediate results) and Ditto [2](clipboard manager) among those you've listed ? I can't live without them on Windows to be honest.
Though my db syncing doesn't always work like a charm, it still gets the job done. Use the freeware version which should be super sufficient for most of the users.
Checkout other tools which are good such as Flashnote.
