I need to use a timer for my pool filter but the filter plug is a Gfci so it won't turn on automatically. Can I replace the plug with a standard plug?

The extra holes in the connector are for wire chaining the fixture to the next fixture. One pair goes to power, the other pair to the next fixture.
You can cut off the connector and strip the two wires (black and white) and connect them directly to the cord with wire twist connectors. These are color coded for the total size of wires in them. Yours plus a cord is likely to be the smallest (blue).
Black goes to black and white to white. Be sure to use a three prong cord with a ground wire, like this:
Secure the green wire to the fixture's metal with a screw (maybe one already in place), or cut the end of the wire, strip it, and use a twist connector to tie it to a ground wire in the fixture. The clamp is a great idea if the edge of the hole in the fixture is sharp.
Originally, in the UK after BS1363 was introduced, there were 1, 2, 3, 5, 7, 10, and 13A fuses but nowadays mostly 3,5 and 13 are used/available.
The plug fuse is to protect the wire between plug and appliance, it is not primarily intended to protect the appliance (which can have it's own fuse or other protections).
So the choice of fuse principally depends on the diameter of the wires between plug and appliance.
However there is nothing wrong with choosing a lower fuse capacity that will also protect the appliance to some degree.

Does the cord/plug-mounted GFCI really trip every time power fails? Or are you assuming it will because other GFCIs do? That is a design choice by the GFCI manufacture, and that would be a rather stupid design choice for a cord-mounted GFCI. For this very reason.
Change the order of things
Right now the sequence is:
Change the order so the GFCI is before the timer.
Since this appears to be an appliance with a GFCI integrated into its power cord, this gives you three ways to do this, in order of increasing badness:
Your insurance company will not like the last two.
