Wanted: cyclocross / gravel bike

I had a wanted up for Cannondale / Specialized cross bikes already but I haven't found anything yet. So opening it up a bit.

I'm planning to try a bit of cyclocross this year, which is probably a mistake. Perhaps a bigger mistake would be doing it on a road bike with skinny slick tyres. So I need a more suitable ride. I assume a cross bike is ideal, but I'm also happy to look at reasonably lightweight gravel bikes as I'm sure it makes little difference considering I won't be going very fast.

Size: Ideally a 54 or M. Def. not 56.
Material: Ideally alu or carbon.
Brakes: canti or disc, happy to consider either.
Condition:Obvs. not interested in damaged carbon frames, but overall does not have to be mint, I'd lean more towards mechanically excellent, I don't want to have to faff around doing too much work. I'm trying to wean myself off needless bike tinkering.
Speeds: specific here, I'd prefer 11 so I can put it on my Kickr occasionally without swapping out cassettes. 1X would be ideal (apparently).
Wheels: clincher or tubeless. Not tubs.

I'm London based. Thanks!

Nice arkose but not quite what I’m looking for.
