What kind of bit is needed for this screw?

A Phillips bit does not make it and a straight blade either.

(I feel that whoever came up with this idea should be covered in honey and placed in an ant mound.) :-)

The bit on the right fit that screw the best.

I went looking thru my screw drawers to find a replacement of better design.

Those screws are like fruit flies. They are everywhere.

A medium size flat-head screwdriver should work fine.

But the preferred usual choice is a Robertson square drive.

And the absolute best is a combination, such as this Klein:

Klein combination tip screwdriver

I have various Klein tools, I do not have this one, I have no stock in them. This is just the first example I found on Amazon showing this type of tip. My electrician uses the Robertson square drive, and most of the time I just pick up a regular screwdriver.

Some of these are actually designed with a little extra slot perpendicular to the main slot, so that a Phillips will work to a reasonable degree, but the one you pictured here does not appear to have that.

That screw will take either a flat blade or a robertson(think #2), (American square) screwdriver.

If flat blade does not work then you need a larger one.

Robertson's were invented to prevent flats from cutting screw driver's hands when they slipped.

Pretty sure its called an ECX bit. It fits perfectly. However, it is a robertson in the center and you could use that instead and it works just as well.

Flat, Phillips, square. Use the square, probably a number one which is the small one.
