I made my own file manager to not have to use Finder so much. It's called WhimFiles and here's the tagline for it:
"Narrow any folder by type, date, and size all at once. Jump anywhere with fuzzy folder search, hover to preview without opening, and browse two folders side by side. No more digging through endless Finder windows."
I've been making native Mac utility apps to solve some of my (and hopefully others') needs.
One is called WhimFiles and is a file manager for Mac that is only 9 MB. It started out with me wanting to clean up my Downloads folder and wanting an easy way to filter files. As I thought of more things I wanted in a file manager I started to add them.
Now the app has dual pane, tabs, fuzzy go-to-folder, batch rename and many other quality of life features. I use it often for my own needs and have also made a few sales (thank you if you've purchased it). The app can be found here: https://whimfiles.com
Another app I've made is called WhimPop and it's a launcher that's shown when you hold down the right-click button (the regular context menu still shows if you only click the button). WhimPop gives the option to add favorite apps, folders and URLs on a rail, plus clipboard history, snippets, a timer and much more. It can be found here: https://whimpop.com
