I'd suggest to do a combination of things.
1 - Put your most used in Keyboard>Application Shortcuts.
2 - Put some in your panel, maybe create two panels if necessary.
2a – Add some Launchers to your panel as you can add as many of the apps in it as you'd like, thereby saving panel space.
You can even add commands in "Add an empty new item"
I don't know if it's true, but I've seen recommendation in this forum to use MX Tweak to move the panel, as opposed to moving it through the panel itself IF you're going to move it.
You can save/backup you panel settings too.
I don't have any experience with this, but possibly consider adding Cairo Dock: cairo-dock.

3 - Put your favorites in MX Menu Editor Favorites, you can change the number in favorites, size too.

The Docklike Taskbar displays what is currently running.
And I've been incorrectly "helping" some on this forum by giving advice to add a Docklike Taskbar when I meant a Launcher – apologies.
HTDH Hope This Didn't Hurt.

Just saw your last post. Do you want two rows or two panels?
I don't know for sure, but I think two rows may work better if the panel is horizontal – I'd move with MX Tweak.
Two panels from panel preferences. You could make some panels always visible, some not, etc.
Since you like to view a lot, possibly consider cairo-dock.
