Personally, I'd go for a rigid core/spc, LG,lifestyle floors and I'm sure someone can recommend others, you are probably looking around £38sqm, but if your floor is fairly good, you save on prep and fitting, plus it's quicker to fit
A decent rigid click would be fine, alternatively a glue down lvt, decent wear layer, .55 or more, surface scratches will still happen etc but keep with a maintenance kit and it will come up as new for many years.
I wouldnt buy online unless you have a fitter lined up. Getting a fitter is the bottleneck. Try calling commercial fitters you never know some of them might do a smallish job.
