> more modifiers and utilize the thumb for way more than the spacebar.

This is true of keyboards like the Moonlander, or the Planck (which is even smaller than OP's keyboard).

But, OP's keyboard has a big spacebar.

I reckon there are two families of "small keyboards": those with a big-spacebar, and those with multiple thumbkeys.

With the big spacebar, I feel vindicated to see the replies linked to say "I don't need F-keys because I don't use them frequently".

Whereas with the Planck, the Planck is as small as it is (as stated on the video on olkb.com) in order to minimize hand movement/stretching from home row.
