Does Apple have keyboard shortcuts to switch between applications in Mission Control? (Instead of hovering over with the cursor)?
e.g., which key combination cal I press to get me from "preview" to "app store?"
There is no keyboard shortcut to switch between applications within Mission Control.
In System Preferences > Keyboard > Shortcuts > Mission Control you can see all of the built in keyboard shortcuts available:
None of which allow you to move between applications in a space.
Mission Control is designed to be used with a mouse or trackpad. If you only use the keyboard, don't activate Mission Control, instead use command + tab to switch between apps.
For anyone wanting a good way to switch windows with the keyboard. I found https://contexts.co/ the best solution out there.
It's incredibly fast and allows you to select windows based on a fuzzy text search or keyboard shortcuts.
In mission control Control+arrow key allows you to switch between spaces

Hammerspoon is a great solution to this problem. Especially being I already had been using it for years. Once you install you can use the lua code supplied in the docs to get started. https://www.hammerspoon.org/docs/hs.expose.html
Once invoked through a shortcut of your liking it assigns and displays a keycode to each of the open windows inside expose/mission control. You can set filters and customize however you'd like.
