I learned with dry paper not skimp on it. I started using Allan Calder's sanding supplies (https://www.sandpapersupplies.co.uk/). Allan's paper (RhinoGrip I think) is so much nicer to use. It doesn't clog up nearly as easily as the Amazon crap and when it does a quick brush with a towel gets it back to almost new again. It might be a more expensive but you use so much less of it.
Unfortunately Allan doesn't seem to do wet 'n dry so I've ordered some from the polishing shop (https://www.thepolishingshop.co.uk/). I think the brand is Matador. If I don't get on with that I'll try the brands you've suggested - thanks!
