No photos but I've got a 1l ish saddle bag from arkel

That takes 2 tubes, pump, tool and a few odds and ends.
one or two bottles on the bike depending on temp/ride length.
Then stuff in pockets is a gilet, food and phone.
Has been fine for some quite long rides - 150milers. Obviously shop/cafe stop helps for more food and water.
In winter I occasionally take my camelbak as it is just easier if you need extra layers, gloves and things.
A simple top tube bag?

Btwin (Decathlon) frame bag. Can mount it above or below, but I find it sways about when mounted on top. About £8. Big enough for tube, tools, phone and keys.

@iainc It just bolts on to the (bottle holder style) holes in the top tube. Plus a velcro strap round the spacers under the stem to provide a bit of extra support.
Tool bottle thingy whatsit under down tube. Phone, credit card and waterproof in pockets. Sometimes gaffer tape a tube to the seat tube as 2 32mm+ tubes are hard to fit in the tool bottles.
For me it's more or less saddlebag & pockets as per road riding, but I do have a small SeeSense handlebar bag if I want to take some extra snacks or a layer. Will prob use it a bit more for carrying binoculars now too.
EDIT: I had one of the ortileb saddle bags that just attaches to saddle rails. It rattled out of the clasp on rough roads so I suspect it would suck for graveaux.
For my sorta gravel bike I have a Wizard Works Lil Presto bag. Pretty much just throw everything in it tube, pump, leavers, phone, keys and all that.

I use my normal road stuff however I do have one of the Kalenji (Decathlon) running belts that I use for MTB rides that I can do with just one bottle - it'd be ideal for a gravel ride. I find it doesn't move about despite me being slim (28" waist) but I have to wear it slightly off centre so the tube sits (comfortably) in the small of my back.
I use it for a tube (external pocket), levers, pump, chain splitter, multitool, keys and snacks. It'd easily take a phone too and I can carry a packable jacket or banana/large snack in the second external pocket.
My setup with toolkeg on downtube...
