Pump and Relay Outdoor Wiring

We recently bought a home that had a shed, which we removed. The shed housed a run of cable to a sprinkler pump at the back of the property. It also housed the pump start relay. The shed is now gone and I have dug the trench to reconnect the power back to the pump. My plan is to put a pedestal next to the pump and attach the receptacle and relay there. See pics.

I have a few concerns:

The pump has a receptacle connection. It is a 20 amp 230v pump. Can I install an outdoor receptacle, plug the pump in, and reliably expect it to work while exposed to the elements? I have never used an in-use outdoor receptacle cover before.

I have read that GFCI is not recommended in this instance. Why is that?

Same thing with the relay. Will the relay be okay exposed to elements? I know they are weather resistant boxes, and I plan to build a sort of roof over the pedestal.

You could install a twist lock receptacle with an in use cover.
There are no 240v GFI receptacles.
GFI protection is not required for that pump.
Doubtful that relay is weather proof.

Some type of lean to sounds like a good idea.
Keeps the pump covered too.

Don't forget if you're putting the relay at the pump..... you'll need the power feed and the 24vac relay wire.
