Layout help

I'm looking for any help/advice. I've been trying to research on what to do but there's so much info I'm just goin around in circles so hoping some experienced people can give me advice.
At the moment I am trying to plan for next year, I have a small part of a garden that's ideal for majority of veg. This part is terrible drainage so when it's wet it's soggy to walk on, but becomes dry when really sunny. And when it's windy it can knock everything over, so I was thinking a raised bed (tried to look at the thread raised beds but can't see the pictures) but I also want flowers around this too to encourage wildlife and to obviously look nice. Can anyone advise how this could be done I'll attach a picture. It's a south facing garden with midday sun (when it appears) hidden by a massive pine tree. I stay in Glasgow, give you an idea of the predictable weather.

Moisure first.
Is this at the bottom of a slope or getting the run off from a garage/shed/drive which puts greater amounts of water than would normally just fall out of the sky? If so you need to address that first with a soakaway or drainage gully.
Given that is not the case or has been addressed the next issue is to help the soil become 'lighter' and able to both drain excess water and retain moisture in the middle of summer to help the plants. This is done with compost and mulch, you can dig it in or even fork some in the trench to double dig at depth for a fast response. OR you can lay thick brown cardboard over the grass (to smother the grass and kill it) and cover that with lots of compost, manure and other organic matter (even put some under the cardboard if you have lots). If you do the mulch now before the wet winter the worms will pull down the organic stuff and make drainage holes without having to dig. In the spring you just plant straight into the compost with do digging at all. Keep adding compost/mulch each season and the ground will not be waterlogged but full of healthy plants.

Getting lots of organic matter is your biggest problem but theres lots out there and autumn leaves will soon be in abundance as well as horse muck.

Which part of the garden are you thinking about? Is it the grass between the raised area/wall and the decking?
If its poorly drained I'd put a couple of raised beds on it. The hedge may have its roots there too, so a bed over it would be good. You can mix and match flowers and veg - really depend on what you want to grow there.
Looking at it, I'd say some bean sticks in a "wigwam", or as a row in front of the hedge and a couple of beds alongside the wall and the deck in a sort of U shape.

It's not on a slope but is very mossy, could this be contributing to the water retention? Once it eventually stops raining I plan to try take it up with a leaf rake. Yeah veggiechicken that part of the garden is the ideal spot. I would like one on the opposite side too but it's a west facing fence so only morning -midday sun. I like the u- shape idea, I love sweet peas so could have that plus runner beans as a row - I tried wigwams this year and ended up a bit straggly, maybe done it wrong.
